About the wheel bolt pattern on the domestic Niva car

The wheel bolt pattern for the Niva 2121, like any other AvtoVAZ model, is an extremely important parameter when selecting new wheels. Using this parameter, you can find out how the wheel rim is attached to the suspension elements of the car.

The size of the wheel arches of this car allows the installation of wheel rims measuring 16 and even 17 inches. By choosing the right products for your vehicle, you can achieve an improved appearance, as well as improve handling and smoothness. In addition, Niva is famous for its off-road qualities. And in order to fully demonstrate them, a high-quality selection of wheels and tires is especially necessary.

Niva 2121 wheel bolt pattern and other important dimensions

Model bolt pattern parameter and its meaning

The model is considered one of the best in cross-country ability. It is also well suited for installing various types of improvements and modifications. Almost all of them start with wheels and tires. Improving any vehicle is an important and responsible procedure, which as a result will greatly improve and exceed the original characteristics. The so-called tuning, which is performed by replacing factory parts and components with new unique ones, gives the car sportiness and visual appeal. In the case of the Niva, most of the improvements are aimed at improving off-road performance.

Almost always, improving the exterior is achieved by replacing the wheels. Their characteristics, such as size, shape and color, can dramatically change the exterior. Successfully and optimally selected wheels can decorate a car well.

Important ! The standard wheel bolt pattern for the Niva is radically different from other cars in the manufacturer’s model range.

Improving an SUV's curb appeal isn't as important as the quality of that improvement. A vehicle with incorrectly selected parts and components can ruin the life of its owner and pose an increased danger to pedestrians and passengers in the cabin. Experts note that improvements installed on the machine should not reduce its operating efficiency. It is recommended to use only original spare parts that meet all necessary quality standards and safety requirements.

As for the disk parameters, the bolt pattern must comply with the specified standard in the technical documentation for the machine. With factory wheel parameters, the car was tested by the manufacturer before being sold. The wheels are designed to work exactly with the diameter of the central hole and the bolt pattern specified in the instructions. Violation of these requirements does not guarantee safe operation.

Note! On a large and heavy Niva car, the use of adapter rings for discs is not allowed.

What standard tires does the Niva 2121 come from the manufacturer?

Car rims are attached to the hubs using bolts. Their number and distance from each other depends on the car model, wheel load and other factors.

On the Chevrolet Niva, the wheels are secured with five bolts. They are located at an equal distance from the center. A bolt pattern is a marking (description) of mounting holes for mounting bolts.

It is characterized by two numbers: the diameter of the circle on which the centers of the holes are located, and their number.

It is important to remember: the nuts on wheel rims are made in a special way and differ from ordinary ones. This is evidenced by a special carving

Its metric differs significantly from the standard one. Nivas use nuts with a diameter of 12 mm and a pitch of 1.25 mm. Moreover, standard turns have a similar pitch, 1.75 mm. Thanks to a small step, the reliability of such a connection significantly increases. Due to this parameter, the self-tightening effect is realized.

This is why it is not recommended to use nuts that were not originally intended for installation on a vehicle. Since larger coils are not suitable. At the factory, the nuts are made so wide that when you screw them onto the stud, it comes out on the other side. The inner part is made in the form of a regular cone.

Due to the design features of the body and wheel arches, it is possible to install wheels of various modifications. Many owners want to install models with a larger diameter than are available. The maximum permissible wheel parameters for which it is not necessary to use an angle grinder to modify the body:

• profile width, mm – 215;
• profile height, mm – 75.

The maximum permissible overhang is 35. When installing a profile with a width of more than 215 mm, the arches will have to be cut in any case. In turn, the minimum permissible offset is 58. These are the wheels that are installed on cars directly at the factory. The optimal solution is considered to be parameter 40-45. It is advisable to familiarize yourself with all the installation details in advance. This way you can avoid wiping. You can see the characteristics in special photos.

Properly selected wheels and tires are the key to stable vehicle performance on the road.

How many holes for bolts on wheels for Niva?

In some sources, the name drilling is also often used and for any car it is denoted by the English abbreviation PCD. To make the term easier to understand, it is advisable to illustrate it with an example. The wheel bolt pattern for Niva corresponds to 5x139.7:

• In this case, the number five means that the appropriate number of bolts are used to secure the wheel;
• The second number 139.7 means that the mounting bolts are located in a circle whose diameter is 139.7 centimeters.

Most novice drivers do not always pay attention to drill data when choosing wheels. In this regard, certain problems may arise. It is impossible to visually determine the diameter size - you need to use a ruler, but a caliper is best. Having measured the size between the holes, you need to insert the obtained data into a special formula and carry out the calculation.

Choosing summer tires

To select the right tires for an SUV, you need to follow the manufacturer's recommendations and take into account the operating conditions of the vehicle.

Tread pattern

The tread on the tires is different, not for beauty. The performance characteristics depend on this parameter. There are three types of patterns:

Symmetrical, without direction. A classic tread option, suitable for driving around the city and on the highway. This pattern is often used on inexpensive budget tires. The characteristics do not depend on the direction of movement and operating conditions. Standard option from the manufacturer.

Symmetrical, with direction. Rubber with a similar pattern is characterized by good grip and effective removal of water from the contact patch. Excellent for high-speed driving, including in rainy and spring weather. They cannot be installed on any hub, as they have a strict direction of movement, indicated by an arrow on the cord. Asymmetrical. The universal pattern is equally suitable for wet weather and dry weather. It is found not only on SUVs, but also on sedans and family station wagons. This rubber has different patterns on the inside and outside

When installing, you also need to pay attention to the inside/outside designation.

Each of the listed tread patterns has both advantages and disadvantages.

Speed ​​index

An important parameter for choosing tires for the Chevrolet Niva. Markings in the form of Latin letters indicate the maximum speed that can be achieved on these tires.

For civilian versions of tires, the maximum speed reaches 300 km/h. It’s not worth considering all of them, since for the Chevrolet Niva, a speed of 140 km/h is already the maximum - its power unit will not be able to handle more. Tires with a high index are much more expensive, and there is no point in overpaying for it.

Load Index

The parameter determines the load that the tire can withstand when driving at maximum speed. This is the weight of a car with passengers and cargo allowed on one wheel. The index ranges from 70 to 120, which corresponds to a load from 335 to 1400 kg. If you plan to transport passengers and heavy loads, then it is better to take tires with a high index. But buying tires with an index that does not correspond to the maximum load allowed by the manufacturer is also not worth it.

Tire carcass

By design, tires can be radial or diagonal. The latter are practically not used today. The letter R in the radius designation indicates that this is a radial tire. There are also reinforced tires designated C (Cargo) or LT (Light Truck). They are usually used to transport heavy loads. You can combine all the available information and choose tires for the summer, guided by three main scenarios:

• Relaxed driving around the city and on the highway. For such conditions, tires with a medium profile, symmetrical tread pattern without direction or asymmetrical with a speed index of up to 140 km/h are suitable.
• Driving at maximum speed. It is better to choose tires with a lower profile and a high speed index.
• Off-road driving. To do this, choose high-profile tires with a deep tread - mud tires.

Bolt pattern tables

To ensure that the car owner does not have to take measurements and do unnecessary work, special tables have been created that already contain data for a specific car.

The disadvantage of doing your own calculation is that you can make a mistake in taking measurements. A difference of a few millimeters after inserting data into the formula can end up producing completely different values.

Due to the fact that various manufacturers create all sorts of variations in the diameter dimensions for bolts, in which the values ​​can be close, you may not be able to make the right choice. For example, instead of 139.7, get close to 140. This means that the wheel is guaranteed not to install, despite the difference of only 0.3 millimeters.

The tables are designed to make life easier for car owners due to the fact that they contain ready-made and accurate data.

Parameters for "Niva Urban"

The Urban model is a modified version of the regular Niva. It has greater cross-country ability and an improved level of comfort for the driver. The dimensions and other parameters of wheels and tires for Niva Urban exactly correspond to the classic model.

The only difference is that the modified version has original alloy wheels installed in the base, while the classic version has stamped steel wheels.

Factory tire parameters:

• 175/80 R16;
• 185/75 R16.

As for the rim sizes and drilling parameters, they are as follows:

• Rim width - 6.5J inches;
• Bolt pattern - 5×139.7;
• Reach - ET 35 mm;
• The diameter of the central hole is CO 98.6 millimeters.

Knowing the significance of the wheel bolt pattern for the Niva, you can easily select a new set of wheels for this legendary domestic SUV.

Types of disks

According to the material and method of manufacturing parts, wheels are divided into three main types:

• Stamped. The simplest and cheapest products are made by stamping from rolled steel. They are inexpensive and, in case of deformation of the rim, are easily restored. However, the stamping is too heavy, which affects the car’s handling and the life of the suspension parts. Also, stamped products bend easily and rust quickly. Price - from 1500 rubles.
• Cast. Wheels made of aluminum and other light alloys are at least 20% lighter than steel. They look attractive, are highly durable and do not rust. But light alloy wheels are much more expensive than stamped ones and are more fragile. Unlike steel ones, they can crack or burst from a strong impact. Price - from 3000 rubles.
• Forged. The difference with cast wheels is that these wheels undergo additional mechanical and heat treatment. After which lighter and stronger products are obtained. Forged wheels are more resistant to corrosion than cast wheels. But they are the most expensive. Price - from 3900 rubles.

How to change a wheel bearing yourself

(as well as the rear) Chevrolet Niva has exactly the same design as old cars, and their repair and replacement are carried out according to the same scheme. Initially, you should go to any car wash, where you should thoroughly wash the entire front suspension under high pressure. For crossovers, this advice is especially important.

• The front of the car is raised using a jack;
• The corresponding wheels, brake pads and calipers are dismantled;
• The hinge pin is untwisted and pressed out using a special tool;
• The bolts from the hinges and nuts are removed.
• After this, you have the opportunity to examine the part for damage and make appropriate repairs. Regardless of whether you plan to replace the bearings, you should change the seals.

After removal, the inner race along with the rollers must be thoroughly washed with kerosene. After this, you will be able to visually assess the bearing damage. It is worth remembering that these parts are replaced only in pairs.

• There is no possibility of adjusting the backlash using a nut (tightening does not help);
• The rollers and clips are heavily scratched;
• Overheating is detected and a hum is observed.

If you observe one of these signs, you need to get new bearings for your Chevrolet Niva. Otherwise, only the lubricant and oil seal need to be changed. Pressing occurs using special nozzles. Do not throw away the old clip, as you will need it to install the new part. If difficulties arise, you can always find one of the many videos on the Internet that demonstrate this process.

Designation R

Chevrolet Niva 15 wheels have a radius from the factory, where R- denotes a radial tire, and 15 is the diameter in inches. The tire size for Niva 2121 is an important characteristic, but you also need to know what the bolt pattern on the Niva is on the disc. You will have to take a larger tire size for the field. The diameter of the holes with which they are attached to the hubs is 5 pieces. The wheel also has a certain width and the larger it is, the greater the offset it will have. On the one hand, the longer the reach, the better, since the Niva 21213 will perform better off-road, but on the other hand, the bearings will wear out quickly.

Exploitation

To ensure that the service life of the wheels is as long as possible, the following rules should be observed:

1. Tires must be properly attached to the hubs
2. It is advisable to drive on a bad road at low speed
3. Check discs for cracks and chips
4. Balance every 10,000 kilometers

To summarize, we can conclude that the best option is to install alloy wheels with a 17 radius on the Niva. With them, excellent cross-country ability of an SUV will be achieved.

It is very important to follow traffic rules on the road. For safe driving on a Chevrolet Niva, it is important that the car has wheels that correspond to the parameters of this car and are provided by the manufacturer, otherwise you will have to constantly change the wheel bearings

Discs should be forged or cast, not too heavy. Wash your car more often, preferably at a car wash. It is important to install tires on your car according to the time of year. Maintain your vehicle and operate it correctly.

Dimensions

Castings are very popular; due to their main characteristics, they are optimally suited for the car. Unlike conventional ones, their price is slightly higher, but at the same time they are quite durable and resistant to corrosion. The size of the wheels on the Chevy Niva depends on your choice, and as a rule, from the factory they have a 15 radius. The wheel size should also be suitable. The positive aspects of casting are that, thanks to its light weight, Niva 4x4 quickly gains momentum, and their braking distance, unlike conventional ones, is reduced. Another important parameter is that in hot weather, thanks to small holes around the entire circle, the brake system is blown and, accordingly, cooled. Models with expensive equipment may already come with cast aluminum wheels.

Profile width

Lada 4×4 2121 Niva (VAZ Niva 2121)
Parameters such as handling and safety depend on the width of the profile.

Increasing the profile width improves vehicle handling, especially at high speed, reduces braking distance, and enhances directional stability. At the same time, high-profile tires are more expensive and increase the risk of aquaplaning and fuel consumption.

Reducing the profile width improves traction on snowy roads or in ruts and reduces fuel consumption. The disadvantages of a narrow tire include worse handling, decreased stability, and increased braking distance. It is highly not recommended to install tires already recommended by the manufacturer.

Wheel chains

You can get out of the mud or overcome a snow drift on regular road tires. That's what snow chains are for. They are fixed on the wheel rims and encircle the tire, allowing it to “cling” more firmly to the muddy ground or loose snow.

Chains are not designed for long trips - they wear out quickly and accelerate tire wear. Therefore, they are equipped with special locks that allow you to attach or remove iron “bracelets” in a couple of minutes.

Reference:

Chains are marked according to the radius of the discs. For Chevy Niva it is 15, 16 or, on non-standard wheels, 17 inches.

Wheel bracelets are very effective and do not take up much space in the trunk. This is a simple, fast and cheap way to increase the cross-country ability of a car on road tires.

How many bolt holes are there on Niva wheels?

Drilling requires 5 holes for five bolts. For a 4x4 field: 5 and 139.7 diameter of the holes in the field. The dimensions are presented in the table:

The first column shows the number of bolts and the diameter of the circle for each car, the second column shows the rim width, and the third column shows the diameter of the hole.

Many drivers do not always pay attention to the specified drilling of Niva disks when choosing wheels. You can allow the dimensions to be inaccurate, a few millimeters may “walk”, and therefore the wheel will not fit tightly. You need to make an accurate calculation, because this is safety!
