UAZ tire pressure table. What is the tire pressure on the UAZ Bukhanka

In Russia, the popularity of domestic cars such as UAZ has not faded for many years. Everyone in our country knows that a loaf is not only bread, and a Patriot is not always a lover of the Fatherland. Well, the UAZ 469 – this utilitarian SUV is generally a legend of the Soviet automobile industry. All these cars have good cross-country ability, and their “survivability” is sometimes amazing, although more internal comfort would be nice.

Every motorist must monitor the air pressure in their tires. For each specific model of a UAZ vehicle, there are standards that are indicated in the vehicle’s passport or placed on the door arches, written on stickers.

Knowing what is the optimal pressure in UAZ tires is necessary in order to have good grip on the road surface and make the car easier to drive. This affects safety and comfort. Equally important is the effect of tire pressure on tire wear and fuel consumption.

Tire manufacturers also indicate recommended values. That is, it turns out that you need to put the wheels on the car according to the car’s passport, and inflate them as the developers of the “rubber” say. This will avoid under-pumping or over-pumping, which can lead to an emergency.

How to properly inflate tires

It is impossible to say unequivocally what the pressure in the tires of a UAZ vehicle should be. After all, several factors will influence the change in values.

What model is the car and what wheels are installed.

For example, the pressure in UAZ Patriot tires with a size of 245/60 R18 should be 1.8 on the front wheels and 2.0 on the rear.

The tire manufacturer also matters.

For example, the pressure in UAZ Bukhanka tires on the front wheel pair will be 1.7 for Yaroslavl tires and 1.9 for other manufacturers, and on the rear - 2.2 and 2.4, respectively.

Pumping also depends on operating conditions and time of year of use.

For example, the pressure in summer tires can be increased slightly, but it must be remembered that when heated, the air expands, so the increase should be within 7%. In winter, on the contrary, it is necessary to lower the level of indicators, just as when driving off-road.

When buying wheels for your car, you need to think in advance about how, where and under what conditions they will be used. It is imperative to take into account the recommendations of car and tire manufacturers in order to select the appropriate tire model and inflate them as required, taking into account all the features.

UAZ “Patriot”: a little about tires and their parameters

It is quite obvious that the tires of a car, like the tire parameters, affect its cross-country ability, stability, and the durability of the chassis. Therefore, so much attention is paid to the competent selection of tires, their correct installation and other factors, among which important is the pressure in the tires of the car.

According to their intended purpose, the following types of rubber are distinguished, which are installed on the Patriot:

all-season;
for dirt;
for winter conditions;
extreme option;
oversized for low pressure.

Pressure table for standard UAZ “Patriot” tires
You should remember the importance of proper balancing when installing tires. This is an important condition for proper operation of the vehicle. It is also recommended to use special devices to improve performance.

To ensure the fixation of the tire along the edges of the rim, a tie-lock is used. It prevents the tire from slipping off the rim, securing it securely. Tyrlock is recommended for use on highways and public roads.

Beadlocks are also installed - mechanical rings that are installed on the disk and prevent the wheel from disassembling in the event of side loads. A beadlock is a means of rigidly securing tires to the bead of a rim. They are used by competition participants to improve maneuverability in extreme conditions.

Bedlocks have the following advantages:

help avoid disassembly;
enable the use of low pressure tires;
easy to install and maintain.

It is necessary to constantly monitor the tire pressure of the Patriot SUV.
The disadvantages of beadlocks include the following factors:

increase in vehicle wheel weight;
lack of possibility of precise balancing;
the need for frequent tightening of bolts;
They are not used on regular highways.

Low pressure wheels

Many drivers, even those with significant driving experience, have no idea what low-pressure tires are and what they are needed for. Basically, only off-road enthusiasts have such information, equipping their “iron horses” with special wheels with increased width.

It is very rare to see cars with such “legs” within the city, and they also try not to drive them on the highway. There are reasons for this:

Driving a UAZ all-terrain vehicle on low-pressure tires on asphalt is not easy.
The maximum speed is 80 km/h.

Externally, the UAZ Patriot, which can often be seen in this form, looks very comical with these “shoes”. But all the touch of irony disappears as soon as you see with what dexterity these seemingly clumsy giants maneuver off-road. Naturally, it is impossible to achieve such agility through mud and potholes with conventional tires.

Features of low pressure tires

Now it's time to learn the secret of low pressure wheels. As an example, let's take AVTOROS M-TRIM tires (900-450x18), their size in inches is: 35.4x17.7 R18. It is worth saying that the invention of such wheels is an attempt to combine the wheels from an all-terrain vehicle and a regular all-terrain vehicle.

AVTOROS M-TRIM (900-450x18)

The former have excellent buoyancy, while the latter have exactly the opposite properties - the designers were faced with a difficult task. After all, it turns out that among the positive characteristics there is only an enlarged contact patch, but there is no powerful group of hooks, there is no hard cord of the sidewalls, but you cannot do without this on the roads.

What solution did the inventors find? They made an unusual tread pattern, and installed an anti-skid device inside the collapsible wheels - this is a thing that prevents the tire from coming off the rim.

To drive on asphalt, the pressure in such tires must be 0.6 atm.
On off-road conditions, such as swamp carpet, sand, snow, the manufacturer recommends lowering them to 0.15 atm.

It should be understood that a Patriot on low-pressure tires will not become like an all-terrain vehicle; if it gets into a body of water, it will simply drown. But off-road, he feels at ease and easily overcomes shallow wetlands, frolics on damp ground and climbs up hills.

Despite the peculiar tread, black soil or clay will still clog it if you drive on it for a long time, but there must be some difficulties, not everyone enjoys the ride. You can see how the car behaves in off-road conditions in the video.

According to UAZ Patriot owners who use similar low-pressure tires, when using wheels it is necessary to follow the manufacturer’s recommendations, that is, operate the car only in certain conditions with the required performance. It is equally important to improve the car itself, for example, strengthen the driveshafts and axle shafts.

In custody

In order for the operation of the car to bring positive emotions, you need to be more attentive to the manufacturers' recommendations. If you control tire inflation in accordance with the standards, this will not only make you feel more comfortable while driving, but will also increase the safety of the driver and passengers, as well as preserve the functionality of some parts of the car longer and save fuel.

The company that produces UAZ Patriot cars has established the following tire pressure parameters:

Tires 225/75R16 K-153, K-155 Front: 2.0 Rear: 2.4

Tires 235/70R16 KAMA-221 Front: 1.9 Rear: 2.2

Tires 245/70R16 K-214 Front: 1.8 Rear: 2.1

The manufacturer did not indicate under what conditions these figures should be considered acceptable.

The manufacturer has established the following weight distribution: – Curb weight 2125 kg. / front axle 1150 kg / rear axle 975 kg – Gross weight 2650 kg. / front axle 1217 kg / rear axle 1433 kg

Wheel balancing should not exceed 1000 g/cm.

Having analyzed this information, we can say with confidence that the pressure recommended by the manufacturer assumes a completely loaded car, because Only a loaded car meets the parameters of higher tire pressure.

Experts argue about what pressure in UAZ Patriot tires is considered acceptable. A good half of UAZ car owners do not share the manufacturer’s opinion on this issue. So, when choosing tire pressure, you should pay attention to the following factors:

1. There is no differential in the transfer case, so you need to make sure that all four tires have identical pressure. Even different loads with the front axle connected can cause the transfer case to break down. Tire manufacturers recommend disabling the front axle when it is not needed.

2. Tire type can also affect pressure. Be sure to check with the manufacturers of the tires you are purchasing about the best pressure for the UAZ Patriot. Buy proven tires for your vehicles, such as yokohama geolandar. Tire pressure is also affected by the size of the vehicle.

3. You should be aware that low tire pressure will significantly increase fuel consumption, as well as increase the load on the transmission and lead to rapid wear of the outer tread. Of course, with low tire pressure the ride is often smoother and more comfortable. When turning and various obstacles, air will escape from tires without tubes and with low pressure, and when hitting curbs, the condition of the wheels and rubber will deteriorate.

4. If, when driving onto a high curb, the disk of your car comes into contact with the curb, then the pressure is clearly not enough for driving through the urban jungle. It is important to know that driving on curbs has a bad effect on the condition of the tires. If a car with low tire pressure comes across an open hatch, it risks damaging the disc.

5. With low tire pressure on the UAZ Patriot, the specific pressure on the ground steadily decreases - this factor pleases off-road enthusiasts, as the vehicle’s cross-country ability increases.

6. With increased tire pressure, fuel consumption decreases, but wear on the tires in the tread area increases and the suspension and fastening systems are burdened with unnecessary work. Elements of the exhaust system may fly off; The mufflers fly off the fastest. Tires develop bulges and bumps over time. If the mounting points of the gearbox and transfer case fail, check the condition of the tires - perhaps the reason is due to increased pressure.

7. It is best when the size of all the tires of the car is the same - it is important to take into account the load. If only the driver is in the car, then the load on the front tires is higher due to the engine and if the pressure in all tires is equal, the front wheels will be less. If cargo is placed in the luggage compartment of the Patriot and passengers are placed in the cabin, the load between the front and rear tires will be changed taking into account the weight distribution.

8. Interestingly, tire pressure is affected by air temperature and sun activity.

9. During active driving, tire pressure may increase due to their inevitable heating. For this reason, the tire pressure of the UAZ Patriot must be diagnosed when the car is cold.

10. As soon as the cold season sets in, it is necessary to check the tire pressure, because... it could have gone down.

11. Off-road enthusiasts should know that when actively driving through the forest and in the complete absence of roads, tires need tubes, otherwise lateral loads will play a bad joke and the air will come out of the tires.

Car enthusiasts often do not pay enough attention to tire pressure. And it must be constantly monitored, otherwise the consequences can be the most unpredictable: from rapid tire wear to impaired vehicle controllability. In fact, the consequences are much greater, and if you do not follow certain rules for inflating tires, you can get yourself into a lot of trouble. But sometimes even experienced motorists don’t bother too much about optimal tire pressure. But each individual car requires a certain amount of air in the tires. And if these indicators do not meet the standards, then the tires and some components of the car quickly wear out.

UAZ Patriot cars are considered very durable and resistant to various loads. They are often used for off-road travel. Different wheel diameters require different tire pressures. For example, tires 225/75R16 K-153, K-155 require inflating the front tires to 2.0 bar, and the rear tires to 2.4. But tires 235/70R16 KAMA-221 already provide for other indicators: front - 1.9 atmospheres, rear - 2.2. Tires 245/70R16 K-214 require a pressure of 1.8 bar on the front axle, and 2.1 on the rear axle. The car manufacturer does not indicate for what conditions these parameters are considered to be the norm. But many car enthusiasts note that such requirements are more suitable for a loaded car. When the car is minimally loaded, the pressure readings should be slightly lower.

Tire inflation

The pressure in the wheels of the UAZ Patriot can be reduced slightly if this is for the benefit of the car and its owner. When severe discomfort is felt during a trip, or rattling is heard in the cabin, the air in the wheels can be deflated a little, despite the fact that the manufacturer has indicated clear parameters. And most UAZ drivers do this because they do not agree with the factory standards.

Many car enthusiasts do not know what exactly can happen if they overinflate or underinflate their tires. The most common problems:

excessive fuel consumption;
controllability problems;
erasing side protectors;
rapid wear of rubber;
possibility of damage to the wheel rim;
possible breakdown of some car components.

But with pumped ones there are already other difficulties:

erasing the middle tread;
loss of controllability;
the appearance of bumps on tires;
rattling in the car interior;
inconvenience of movement.

It is precisely because of these reasons that it is worth constantly monitoring tire pressure.

The amount of air inside the wheel should only be checked when the tires are cold, otherwise the readings will be incorrect.

Ambient temperature also directly affects the atmosphere inside the wheel. For example, in winter, when the air temperature drops, the tire pressure also decreases. In summer, on the contrary, it rises. Therefore, measurements must be taken at least once a week. This can be done with a pressure gauge, which is sold in every car store. Such a device comes in several types and accuracy classes. Therefore, when purchasing, special attention should be paid to accuracy, since the further correctness of its operation depends on this.

Wheelbase UAZ 469

This all-terrain vehicle, developed for army command personnel, never provided the required level of comfort. And the engineers of the automaker’s factories themselves did not set themselves such a function. However, when this car corresponded to its era and was not yet outdated, it was one of the most off-road passenger vehicles in the world. Such success throughout the entire period of operation was ensured by the wheelbase of the UAZ 469:

UAZ 469

While many foreign brands were equipped with a comfortable MacPherson strut suspension in the form of multi-link systems, the UAZ was equipped with standard shock absorbers on springs on the front axle, and cargo springs or piston shock absorbers with combined hydraulic and pneumatic functions on the rear axle. Such simple systems worked almost flawlessly and were less susceptible to rupture, loss of fluid and other malfunctions characteristic of more modern cars.
The latest versions of the UAZ 469 were also supplemented with a vehicle lateral stability stabilization system, which is associated with a change in the manufacturer’s priorities, since it began to be widely used by the civilian population.
Considering the dimensions of the 5-door version of 4025 mm, which automatically made it a compact SUV against, for example, the Toyota LC200, whose length exceeded 5 meters, the wheelbase of the UAZ 469 was only 2.38 meters. With such a distance between the axles, the car had a much greater chance of overcoming significant elevation changes and not sitting on the bottom.
The width of the wheelbase was also impressive, measuring 1805 mm. This kept the car on the road, often keeping it from tipping over at speed or when negotiating difficult areas.

Wheelbase UAZ 469

Such a powerful suspension was capable of supporting not only the dead weight of a fairly heavy car - from 1.7 to 1.8 tons, but also up to 700 kg of payload. As practice has shown, a UAZ can be operated at maximum load for more than 10 years without major repairs.
One of the main advantages of this car is its ground clearance, which is achieved due to the special design of the suspension, hubs and wheels themselves on the UAZ 469 with tires. In modifications intended exclusively for military purposes, the ground clearance of the all-terrain vehicle reaches 300 mm, and in the civilian version, adapted for milder road conditions, it is reduced to 220 mm (this relaxation applies to the UAZ 460B version).

Important!

The famous domestic SUV is unlikely to satisfy fans of a comfortable ride with a soft leather interior, air conditioning and a range of various options. However, from the point of view of cross-country ability and other driving characteristics, it will be an ideal vehicle.

Tire pressure of UAZ “Bukhanka”

According to the passport, the atmosphere indicators inside the wheel should correspond to 2.2-2.4 bar. But such measures are typical for city roads. For off-road use, a lower pressure is suitable. Fans of trips outside the city note that the recommended parameters are not very suitable for such roads. The car drives very hard and you feel discomfort while driving. But if the car is expected to be heavily loaded, then air will have to be added to the rear tires. As the tire diameter increases, tire pressure decreases.

The UAZ-3303 model, according to the manufacturer’s recommendations, provides the same pressure in all wheels, which is 2.0 bar. But as the load increases, it must be raised to 2.2 atmospheres. These parameters are typical for the summer period. But in extreme heat, you should carefully monitor the indicators, as the amount of air in the tires increases in summer. And therefore, before the trip, it should be checked and lowered a little if necessary.

On a note!

If the check is planned after the trip, then this should be done only after the car has been idle for two hours. During this time, the wheels will cool down and the pressure in them will stabilize. Owners of such cars recommend deflating the tires a little when driving off-road, but only by no more than 0.3 bar. This will ensure a smooth ride and comfortable movement.

What pressure is recommended for UAZ Patriot tires

The optimal pressure in UAZ Patriot tires depends on the configuration and load of the vehicle. The factory has set a recommended figure of 1.8 to 2.4 At for the standard version and pickup truck. Moreover, the table of values is relevant for asphalt roads. On dirt roads or bumpy areas, many motorists adjust the pressure based on personal preference.

For off-road use, users set about 1.8-2.0 At, which softens the ride and improves comfortable performance (some complain that it shakes a lot). Changes are also made in the pickup version - at the recommended pressure and an empty body, the rear axle of the car bounces strongly - this interferes with control, drivers often lower the tires to 1.8-1.7 BAR. In case of increased load on hard, level surfaces, on the contrary, pumping is done to 2.4-2.5 kg, so the vehicle rides as easily as possible - dynamics and handling are improved, and fuel is saved.

About mud tires on UAZ

You also need to carefully monitor the amount of air in the tires during temperature changes. In summer, at long distances, it is advisable to bleed 0.3 kg from all wheels. This is done for road safety and to prevent the cylinder from exploding, which is explained by the heating of the oxygen - the volume increases, as a result, the gas pressure inside the tire increases.

In winter it's the opposite. During cooling, pumping is required on average by +0.3 units every -10-15°C decrease in ambient temperature. The changes are especially noticeable when storing cars in garages. Inside the warm box, the pressure gauge readings will be within normal limits. But when driving out into the cold, the pressure drops sharply by 3-4 tenths and then the car moves on flat tires.

Tire pressure in UAZ "Farmer"

The UAZ “Farmer” tires need to be inflated on the rear axle to 2.3 bar, and on the front axle to 1.9. Such indicators are typical for an unloaded car in winter. But everything depends on the diameter of the wheel, since when it changes, the pressure also changes. For example, 245/70 R16 tires require 2.1 bar on the rear axle and 1.8 on the front. The wheels are 245/60 R18 and are pumped up to 1.7 atmospheres at the front and up to 1.9 at the rear. As the load increases, the pressure increases by approximately 0.8 bar in all wheels.

What wheel sizes does the manufacturer recommend to install?

The UAZ 3909 Bukhanka 1985 .. 2022 2009 2.9i car is equipped with 6Jx16 ET22 rims assembled with 225/75 R16 tires as standard. Where:

6J - rim width in inches;
16″ — tire diameter in inches;
ET22 - disc offset in millimeters.

The vehicle tire marking 225/75 R16 is deciphered as follows:

225 — profile width (cross section of the tire) in millimeters;
75 — profile height as a percentage of its width;
R - radial cord winding;
16 is the tire diameter in inches.

Using the recommended tire sizes will help you avoid problems with handling, safety and other difficulties. What non-standard sizes can be supplied? Refer to the table; it indicates possible acceptable alternative sizes for tuning. Although there are other options that we have not described in the table. For example, wider discs of the same diameter. Or install wheels of the same width, but with a larger diameter, which is quite popular among car owners. The choice of discs is huge; you can find copies with the same parameters, but with an overhang 1-2 millimeters more or less. It is not possible to list all the options.

Pressure on UAZ "Hunter"

It is this modification of the car that provides the same pressure indicators for all wheels, whether the car is loaded or not. For wheel diameter R16, the recommended values in winter are 1.9 atmospheres, and in summer - 2.0 bar. With increasing load in winter, the pressure rises to 2.1 bar, and in summer - to 2.2. There is no significant difference between performance in cold and hot weather. But you still need to try to adhere to the manufacturer’s recommendations.

Particular attention should be paid to the inflation of all wheels, namely the same indicators in all tires of the rear and front axle. Uneven pressure is the worst thing that can happen to wheels. In this case, the risk of accidents increases significantly, and on top of that, the likelihood of injury to other road users increases. Therefore, it is necessary to check the pressure in all tires and be sure to adjust the indicators to the recommended ones.

Do not neglect simple rules regarding tire pressure. If you have no idea about the manufacturer’s recommendations, then a hint can be found on a special table that can be placed on the driver’s door or gas tank hatch. It indicates the optimal indicators for a certain tire diameter and vehicle load. By following these instructions, you will not only increase the service life of your tires, but also protect yourself during your trip.

Vehicle wheels are one of the most significant structural elements. Especially when it comes to off-road driving. Thus, car tires are made as stable as possible both on the road and on rough terrain. Owners of fairly popular tires eventually change their original tires to models that are more suitable for specific operating conditions. At the same time, it is very important to achieve optimal tire pressure, otherwise driving a car will not be as comfortable and safe.

And here it is worth understanding that the standard indicators of 1.8 or 2 atmospheres are not suitable for all cars in a row. There are a lot of factors to consider, and only the manufacturer can determine the optimal pressure level.

Before determining tire pressure using your passport, you need to understand that there are the following types of rubber for this vehicle:

all-season. Suitable for use in both summer and winter;
extreme. Differs in increased size and low pressure;
mud. It is installed for off-road driving;
winter Helps overcome snowy sections of the path;
road Suitable for driving on asphalt or highways in summer. Demonstrates poor performance in winter and off-road.

It is also worth understanding that all rubber models differ in their technical characteristics, such as width, diameter, profile type. All this affects the tire pressure of the Patriot.

Video review of UAZ Patriot tire pressure:

Modifications of tires suitable for UAZ Patriot

Depending on the surface the rubber is intended for, the pressure readings will be different.

Road - for good routes and highways where there are no off-road areas. In principle, suitable for dry dirt roads. For such tires, the pressure can be slightly increased relative to the standard one - literally by 10%. As a result, the speed potential will be damped significantly less.

In summer tires, the pressure can also be increased slightly, but due to operation at high temperatures, it is better not to increase it by more than 5-7%.

Winter tires are designed to pass difficult sections of the road with uneven pavement density and a high risk of slipping in snowdrifts, so the pressure in winter tires should be low. The gap between standard pressure and for winter tires can reach 12%.

In principle, for so-called mud tires, which are easy to drive off-road, the tire pressure should also be the same as for winter tires. The record low level of pressure in such tires can reach 15% of standard values.

By inflating the tires using a compressor or lowering the pressure in them, it is impossible to achieve ideal driving characteristics. What's the secret? In the end, no, because there are still factors related to tires that affect the Patriot’s behavior on the road. Before experimenting further, we suggest answering the following questions:

Do you measure the pressure in one, so-called control tire, or in all? If the car “goats up” and loses control, or, conversely, slows down during acceleration, then it is likely that the pressure in one, or even all, tires is very different. This means we measure and inflate the front and rear tires to the same level.

Have you already covered 10,000 km on your Patrick? This means it’s time to resurface the front and rear wheels to balance out the wear. Traction 4x4s love to eat up the front tires.

Are all your tires the same size? Only a small run-up is allowed for a pair of front wheels relative to a pair of rear ones. And that's all, i.e. there should not be different wheels in front or behind.

Have you done balancing recently? If you can boast of brand new tires, then after 500 km of running-in you should go to the service station; if you are not going to install new ones yet, then stop by for balancing at least once a quarter.

If you follow these simple rules and follow the table of recommended UAZ Patriot tire pressures given below, you can insure the transmission, axle and engine from premature wear, as well as adequately save fuel.

Standard parameters

For those who want to know what tire pressure should be, then you need to familiarize yourself with the manufacturer’s recommendations. At the same time, the indicators are slightly different for different modifications of transport.

2.7 liter petrol engine

Front wheels:

225/75 – 2 atm.;
235/70 – 1.9 atm.;
245/70 – 1.8 atm.;
245/60 – 1.8 atm.

Rear wheels:

225/75 – 2.4 atm.;
235/70 – 2.2 atm.;
245/70 – 2.1 atm.;
245/60 – 2 atm.

2.2 liter diesel engine

Front wheels:

225/75 – 2.2 atm.;
235/70 – 2.2 atm.;
245/70 – 1.9 atm.;
245/60 – 1.8 atm.

If you want to know what the pressure should be in the rear tires with a 2.2-liter engine, then these parameters are fully consistent with the gasoline version with a 2.7-liter power unit.

It should be noted that the parameters directly depend on the curb weight of the vehicle. The total weight of the SUV should not exceed 2600 kg, the load on the front axle should reach up to 1217 kg, on the rear axle – up to 1430 kg.

To make driving your car safe and comfortable, you should constantly monitor the condition of the car’s wheels.

After all, this detail directly affects the driving process. At the same time, there are several nuances regarding tires that will allow you to achieve the most efficient and reliable operation of your car:

use wheels with the same width and diameter (or you can install the same models in pairs at the front and rear);
You can find out that the nipple is leaking air using soapy water. in case of air bleed, it is necessary to replace the nipple or install a special cap;
check the pressure in all 4 wheels, not just one;
Even on an all-wheel drive SUV, the front wheels will wear out faster. As a result, it is worth changing the position of the tires every 10 thousand km;
after running in new tires, balancing must be done (about 500 km after purchasing the tires);

the pressure parameter depends on the level of wear of the engine, transmission, differential and axle. In addition, all these factors affect fuel consumption.

Important units

Let's start with the fact that each car has its own rules and regulations regarding what operating pressure the tires should have. The norm is 2-2.4 atm, but everything is relative and varies depending on the parameters.

Therefore, if you have a VAZ, Mercedes, Toyota, Gazelle, Ford, Volkswagen or some type of truck, you need to look for a special sticker.

There is no universal formula even for a bicycle, car or some kind of motorcycle, for example. Therefore, UAZ Bukhanka, UAZ Patriot, Renault Duster and any other vehicle, including all-terrain vehicles, rely on the manufacturer’s recommendations. Factory stickers must be on all cars. But sometimes it wears out, wears out, or falls off. In such a situation, check the instruction manual for your model. Recommended pressures are indicated in this literature.

Now let's move on to what units of measurement are used. In Russia, for example, like many other countries, the unit of measurement is BAR (atmosphere). 1 atm equals 1 kgf/cm2. But if you go into details, then in 1 atmosphere there are 1.013 bar. In practice, it is not so important how much error there is between them. These units are equated to each other.

But in the USA they use the PSI unit. It shows the number of pounds per square inch. If the car is from the USA or the car contains recommendations for pressure in PSI, there will be no problems with conversion to conventional units.

To do this, just divide PSI by 14.5. That's all, the translation system is extremely simple.

How is pressure measured? The most common device is a pressure gauge. Every motorist has it, it is inexpensive, but it shows the pressure with a slight error.

To obtain the recommended operating pressure when the pressure gauge shows a lack of air inside the tires, drivers use:

pumping is a pump that pumps air by working with arms or legs;
compressor - connects to a power outlet or is powered from the on-board network;
equipment at the service station.

Features of wheel inflation

But it’s not enough to know what pressure should be in UAZ Patriot tires

. You also need to understand what rules should be followed when inflating wheels. Here are the following recommendations:

When pumping, take into account the characteristics of the rubber. Often the pressure rating is specified by the tire manufacturer;
if the pressure level decreases slightly, this will have a positive effect on the vehicle’s cross-country ability;
a decrease in pressure leads to accelerated wear of the transmission, and fuel consumption also increases. Yes, driving with flat tires is somewhat more comfortable, but the strength of all negative effects on the tires increases;
You should not use all-wheel drive all the time. This increases the load on the front tires; in addition, the transfer case wears out;

Tires should be inflated and pressure checked at an ambient temperature of 0 to +20 degrees. Otherwise, the error will exceed 10 percent, so the results will be extremely inaccurate.

A short summary

Finally, I would like to add that for stable operation of the vehicle, as well as good off-road performance, it is necessary to monitor not only the suspension and chassis, but also the tire pressure.

It is this indicator that largely affects the stability of the SUV, so it is worth constantly maintaining the pressure at the optimal level.

Created on the basis of an SUV, a car with a minibus body UAZ-3962 (3309), in popular expression. The UAZ bunker has become the most widely used. Despite the unusual appearance and technically outdated design, due to its high cross-country ability and unsurpassed ability, the machine is used as a workhorse and is currently in production. Ambulance service, brigades of the Ministry of Emergency Situations in Forestry and Agriculture. all this applies to this car.

Given the difficult conditions, increased requirements are imposed in those conditions when tires are selected on the UAZ drum. Conditions when a vehicle primarily operates on urban asphalt roads are significantly different from off-road conditions in rural areas. In addition, rural roads vary significantly depending on the season.

The history of the “loaf” and its advantages

Last year the 60th anniversary of this “people's” car was widely celebrated. Few people know that the first “loaves” were representatives of another UAZ family - the UAZ-450, produced until 1965. In 1966, changes were made and the updated UAZ was assigned a new index - 452. For more than 50 years, the outline of the model’s body has remained unchanged. By the way, the onboard modification of the UAZ-452 is called “tadpole”.

The design and level of comfort in this UAZ model are spartan, but the car is not designed for comfort. But in other respects, this is a unique car, combining the size and price of an economy-class passenger car, the capacity of the cargo part, which will give a truck a head start, and the cross-country ability of the UAZ-452 is such that residents of many remote and hard-to-reach areas, foresters, fishermen, and hunters are ready to pray for "loaf".

Wheel size on UAZ

Regular tires on the UAZ drum are installed with the following size: 225/75 R16, and in some periods the car was equipped with 235/74 R15 tires. In any case, it should be taken into account that the production diameter of the disk should be in the range of 29-33 inches. This size does not lead to additional changes to the car's design. In addition, the steel disc must meet the mounting size requirements of 5×139.7.

There are cases where the tires were used on a rim size R17, but with the lowest tire. However, due to the large selection of standard tires of any model, this practice is not widespread.

If the vehicle is overloaded or when the suspension is moved to its maximum, even when setting the tire to normal size, the rubber band touches the wheel arches. This situation is not critical and there is no serious destructive effect on the rubber.

Taking into account the prevalence of the vehicle and the most varied operating conditions, a wide range of tires is provided for installing the UAZ bunker. On the market there are not only categories of household, but also imported tires for UAZ. There are 3 main categories:

What non-standard sizes can be installed

Due to the variety of tire choices on the automotive markets and the popularity of standard tires for the UAZ Bukhanka, there is no need to install large wheels, for example 17 or 18 radius.

Moreover, without changing the suspension height, this type cannot be installed. Therefore, as a rule, the tire size recommended by the manufacturer is used.

It must be said that some craftsmen still replace wheels of 15 or 16 radius with a larger size. However, this cannot be done without upgrading the wheel arches, since otherwise the wheels will touch the body at the slightest unevenness of the road surface.

Line of domestic tires

Among the domestic versions of rubber mass models, the following brands are presented.

Universal tires on UAZ:

Bel-24 235/75 R15. The Belarusian analogue has good average characteristics in all respects, fully justifying the purpose of the tire as a universal one. High wear resistance is noted, and work experience allows us to talk about a resource of 60 thousand km.
I-502 has a size of
225/85 R15. The load capacity is 950 kg and the maximum speed. 150 km/h.
"Ya560" provides a maximum speed of up to 180 km/h.
"I'm 357A." This is a radial version of the above rubber, which is characterized by better speed and can withstand a higher load capacity of up to 1060 kgf. This type of tire is a little softer and, with a similar profile, handles muddy driving much better. One can note the good stability of the exchange rate on the road.
"Ya245" and "Ya245-1" have a size of 215/90 R15. This tire brand is characterized by a low top speed. 110 km/h and a relatively low weight of 775 kgf.

225 — profile width (cross section of the tire) in millimeters;
75 — profile height as a percentage of its width;
R - radial cord winding;
16 is the tire diameter in inches.

At the same time, the bolt pattern for all types of wheels is the same - 5 × 139.7. Thus, all the disks are fastened with five bolts and the distance between them is exactly one hundred and thirty-nine point and 70 hundredths millimeters. The diameter of the car's hub is 108 mm.

Standard tire pressure is 2.3 / 2.1 MPa.

Rubber for use on mud

Among the requirements that can be set when choosing tires for use on bad roads, you can name:

developed lugs;
weight not exceeding the permissible value for the car;
permissible width no more than 250 mm;
affordable price;
Resistant to external influences of the tire sidewall.

"I-502." It has a number of advantages: low noise level, good handling on all roads and low rolling resistance under good road conditions. This model adequately copes with resistance to mechanical damage.
"I-506". It has good longitudinal displacement resistance and excellent heading stability. It has a low noise level and additionally allows you to screw in studs in winter. My only criticism. wheel stiffness.
"I-520". Another worthy representative of rubber on UAZ. This tubeless model allows the car to confidently hold the road and operate in different conditions. The noise from the rubber does not exceed the sounds of the transmission. This tire has good self-cleaning properties, which is very important for an off-road tire.

A relatively new model was the Ya471 model. The tire provides a smooth ride, slightly absorbing small bumps. Provides good exchange rate stability and low noise levels. Decent performs not only on dirty roads, but also on sand. Comments on this model include its difficult balance.
Excellent tires for bad roads. this is type "I192". This is one of the best tires for mud. However, the model is somewhat noisy on asphalt and does not operate smoothly.
"I409". This rubber on UAZ is suitable for use at any time of the year. The model copes well with mud, but also feels comfortable on snowy roads. The indicators are a little worse on clear ice, but you can handle the car while driving.
The Ya358 model is intended primarily for installation on the front drive axle. This bias tire is not very fast. But it handles rough roads well, except in wetlands where it can dig on its own.

The best summer (mud) tires for the UAZ “Bukhanka”

In most cases, for the UAZ-452, owners prefer to choose not summer tires, but mud or all-season tires, for driving not only on a simple road, but also on mud and sand.

The BF Goodrich Mud Terrain T/A KM3 is definitely one of the best tires for mud driving. The price is quite high, but the quality matches it. For 2022, the cost is 13,000 rubles. A rather rare feature for this type of tire is low noise level. When driving at high speeds it demonstrates excellent control. The wheels are also characterized by increased wear resistance, which justifies the high cost.
Michelin Latitude Cross - this type of tire is firmly established between premium and average price parameters. Tires 225/75 R16 108Н8500 on average cost about 7800 rubles. The tires are not fast, but for this car this is a minor point. Stable on any type of road surface, regardless of weather conditions. The tread pattern implies a long service life, while performance parameters do not suffer in any way.
Nokian Rockproof - average price 8000-8200 rubles. Tough, durable, the tread is designed for traveling to places where there are no roads. The protector is adapted for movement on water. The tires have special stone repellents built into them.

Kumho Road Venture – imported tires at an affordable price. The average cost is 5500-6000 rubles. Very soft ride, excellent handling at high speeds. The tires allow you to navigate through even the most difficult recesses with stability and without hindrance.

Bridgestone Dueler is a fairly economical model for a leader in this industry, priced from 7,000 rubles. This rubber does not have any advantages or increased advantages, but there are no complaints about it either. This model was created using the latest technologies, taking into account all the required operational parameters.

To summarize, it should be said that the UAZ-452 “Loaf” is an excellent option for lovers of hunting and fishing, an excellent companion when traveling in off-road areas. The car can be successfully modernized externally and technically.

The body is somewhat reminiscent of a “minivan” rather than an off-road vehicle, but this in no way prevents it from overcoming difficult road obstacles. This car is durable, because it is not without reason that the equipment and appearance have remained virtually unchanged since the beginning of its production.

Pressure indicators

Compliance with the level of air pressure in the tires affects, as is known, not only the wear of the wheel tread, but also the performance of the car as a whole. An important consequence is that tire pressure monitoring is carried out when the tires are cold. After a slight run, the controlled parameter may differ by 2-3 tenths of the norm.

The recommended tire pressure for off-road tires on the front wheels is 1.7 atmospheres for tires with the index (Yaroslavl) and 1.9 for other manufacturers. For the rear tires, the tire pressure is set similarly to 2.2 for Yaroslavl tires and from 2.4 to 2.5 for other manufacturers.

Recommended tire pressures

To achieve the full potential of your vehicle, you should select the optimal tire sizes and maintain them at the tire pressure recommended by the manufacturer.

The tire pressure on the UAZ-452 should be no more than 2.5 atm. For the front wheels, the pressure indicator should be slightly lower than in the rear.

The table shows the pressure indicators for the front and rear wheels.

Tire and wheel sizes for UAZ Patriot 2012
