Types and parameters of VAZ 2107 rims

All VAZ 2107 car owners know that choosing the right wheels for your car is very important. Not only the quality of control, but also safety depends on this choice. That is why a certain type of tire is provided for each season: summer or winter. But for those who want to save money, all-season tires have been specially created that maintain high quality maneuvering in any weather. Let's figure out how to properly “shod” your iron horse, consider such concepts as “radius”, “caps” and “bolt pattern”.

Wheel disks

A car's wheel rims are part of its suspension. Like any other detail, they have their purpose.

Why are disks needed?

Wheel rims perform several functions at once:

• transmit torque from hubs or axle shafts to tires;
• ensure uniform distribution and compaction of tires around their seating circumference;
• contribute to their correct position relative to the car body and its suspension.

Types of rims

Today, there are two types of rims for car wheels: stamped and cast. The former are made of steel, the latter - from alloys of light but durable metals.

Stamped discs

Each type of wheel rim has its own advantages and disadvantages. The advantages of stamped ones include:

• low cost;
• reliability;
• resistance to shock loads;
• absolute maintainability.

In order to buy a regular “stamping”, just go to any auto store or market. A huge selection, low prices, constant availability on sale - this is what the undemanding car owner needs.

Stamped discs are reliable and maintainable

There is often no need to buy steel wheels, because they are practically eternal. It is almost impossible to break them. The main malfunction of such disks is deformation due to the wheel falling into a hole, hitting a curb, etc. However, this problem is solved by rolling it on a special machine, and at home - by leveling it with a hammer.

A deformed stamped disk can be easily repaired by rolling it on a special machine

As for the shortcomings, there are fewer of them. Basically, motorists note the lack of aesthetics and individuality, as well as the heavy weight, which affects fuel consumption. As for the appearance, indeed, the “stamping” does not differ in either design or attractiveness. They are all the same. But the heavy weight is a controversial issue, since it was taken into account when developing the car, therefore, the engine characteristics are designed for it.

Alloy wheels

Alloy wheels, first of all, give the car its individuality. With them the car becomes more beautiful and looks more modern. It is this factor that most influences the result of the choice between “stamping” and “casting”.

Alloy wheels are lighter and have a custom design

In most cases, car owners, when buying alloy wheels, do not even suspect that such products do not bend like steel ones under critical load, but split. They can, of course, be restored later using argon welding or other technologies, but it will not be possible to return them to their original technical characteristics.

In most cases, restoration of alloy wheels is impossible

Freelance options

Innovative light alloy models are divided into 3 categories based on their manufacturing method:

• cast;
• forged;
• prefabricated

Cast ones are made from alloys based on aluminum or magnesium, which allows them to reduce their weight by a third compared to standard versions. The fragility and inelasticity of the material upon impact leads to chips or even bursting of the wheel.

Forged products are distinguished by increased strength and lower density due to hot stamping technology. Deformation requires a lot of force, but the inflexibility of the material forces the suspension to take on the full force of impacts when driving on a bad road.

Basic parameters of rims for VAZ 2107

Each part of any mechanism has its own characteristics and parameters, according to which it is actually selected. Discs are no exception. These parameters include:

• diameter;
• width;
• departure;
• hub center hole diameter;
• bolt pattern;
• drilling

  
  Wheels of different cars have different parameters

Disc diameter

Diameter is the main parameter that determines the possibility of installing a disk on a specific car. Standard VAZ 2107 wheels have a diameter of 13 inches.

The diameter of the disc determines its size

Naturally, the larger the wheel size, the better the car looks. Moreover, with larger rims, the car “swallows” small holes and road potholes better. On the “seven” you can install wheels no larger than 14 inches in size without changing tires or modifying the chassis.

Disc width

The width of the rim, or rather its rim, characterizes the width of the tire that can be used with it. The standard width of the “seven” disk is 5 inches, but parts up to 6 inches wide can be installed.

The diameter and width together determine the size of the disc. In the marking it is designated as follows: 13x5, 14x5, 15x5.5 or vice versa: 5x13, 5.5x14, etc.

The width of the tire depends on the width of the rim

Disc offset

Reach is probably the most difficult characteristic to understand. It determines the distance from the interface plane of the part with the hub to the conventional plane dividing the disk rim in half. Depending on the model, discs can have either positive or negative offset. In the first case, the mating plane of the part does not cross the conventional boundary, which divides it into two equal halves. Looking at a car equipped with wheels with a positive offset, it will seem to you that the wheels of the car seem to be recessed inside the arches. With a negative offset, on the contrary, the mating plane shifts toward the longitudinal axis of the car itself, and the disk “sticks out” outward.

The standard “seven” disk has an offset of + 29 mm. However, for this parameter a standard deviation in one direction or another is provided, equal to 5 mm. In other words, the VAZ 2107 will fit wheels with an offset from + 24 to + 34 mm. The amount of overhang is measured in millimeters and is indicated on the marking as follows: ET 29, ET 30, ET 33, etc.

With a positive offset, the wheel seems to be recessed in the arch, with a negative offset, it sticks out.

Changing the offset value of the “sevens”, most often in a negative direction, is used to give the appearance of the car a sporty style and aggressiveness. But here it is important not to overdo it. The fact is that when the offset changes in one direction or another, the distance between the point of attachment of the wheel to the suspension and the support point on the road surface also changes. And the more the standard distance is changed, the greater the load the wheel bearing will be subject to. In addition, the changes will also affect the car’s handling, and this is no longer safe.

Center hole diameter

Any wheel rim is designed for a certain size of the hub, or rather, its centering flange. It is on this that the disk is mounted with its centering hole. For "seven" discs, the central hole has a diameter of 58.5 mm. In standard labeling this is designated as “DIA 58.5”. No deviations are allowed here, but some tuning enthusiasts manage to install on VAZ 2107 wheels with a smaller hole diameter by boring it, or a larger one by using special centering rings.

Centering rings are used when installing disks with a large diameter centering hole on a car.

Bolt pattern

A parameter such as the bolt pattern indicates the number of holes for mounting the disk and the diameter of the circle along which they are located. The factory 7 wheel rim has four holes for mounting bolts. They are located on one circle, the diameter of which is 98 mm. On the marking the bolt pattern is indicated as follows: “LZ/PCD 4x98”.

As you understand, installing wheels with a different bolt pattern on a VAZ 2107 simply won’t work, especially if its values ​​differ not only in the size of the circle, but also in the number of holes. However, there is a way out, and more than one. The first option is to use special spacers between the disc and the hub. Such spacers have two bolt patterns: one standard for fastening to the hub, and the second for mounting the disk. The second option is suitable only for disks with the same number of bolts and a slight deviation from the diameter of the circle on which they are located. During installation, naturally, problems will arise with tightening the bolts at the final stage. It will not be possible to tighten them completely, which is why the wheel will dangle while moving. But this problem can be solved using special bolts with an offset center. You can either buy them or order them from a familiar turner.

The bolt pattern includes the number of mounting holes and the diameter of the circle on which they are located

Sverlovka

Such a parameter as drilling is necessary so that the car owner, when buying wheels, does not make a mistake with the size of the mounting holes. If they are larger than the diameter of the bolts, the disc will not fit tightly and will begin to wobble over time. If they are smaller, the bolts simply will not fit into the holes. The diameter of the holes for the mounting bolts in the standard 7 wheels is 12.5 mm. For fixation, M12x1.25 type bolts are used.

Drilling determines the diameter of the disk mounting holes

Which cars will fit wheels on the VAZ 2107?

Unfortunately, there are very few cars that have the same wheel parameters as the 7. VAZ 2107, in this sense, is almost unique. And it’s not at all about their diameter, width, or reach. It all comes down to the bolt pattern and the size of the hub hole.

Table: cars with similar wheel rim parameters

As for domestic cars, standard alloy wheels from VAZ 2112, VAZ 2170 can be installed on the “seven” without modifications. They have similar parameters.

But you don’t have to waste time searching for suitable stock drives. Today you can freely buy wheels of a wide variety of designs, made from various alloys. The cost of a set of good “wheels” for a VAZ 2107, depending on the characteristics and manufacturer, varies from 10 to 40 thousand rubles. Not cheap, of course, but beautiful.

Is it realistic to install sixteen-inch wheels on a VAZ 2107?

Probably, everyone who had to see the “seven” on sixteen- and even seventeen-inch disks was very interested in how they were “dragged” there. It's actually simple. In some cases, the owners of such cars do not even digest the arches. It's all about the height of the tire, which is expressed as a percentage of the height of the rubber profile to its width. And if for a stock tire it is 70%, then in order to put fifteen-inch wheels on the “seven”, you need to put rubber on them with a height of 40–50%.

When installing larger diameter wheels on a VAZ 2107, low-profile tires are used

To install sixteen- and seventeen-inch wheels, it is better to raise the car a little using special spacers for shock absorbers, or increase the size of the arches by cutting them out. As for the tire profile height, it is better if it is no more than 25%.

What wheels were installed on different bodies and configurations?

When selecting new wheels for any car, including the domestic VAZ-2107, it is necessary to take into account a number of factors specific to this particular model. Traditionally, most cars that rolled off the Volzhsky Automobile Plant assembly line had the most budget-friendly wheel options. The VAZ-2107 was equipped with 13-inch stamped steel elements with standard tires in size 175/70R13.

Starting from 1982 until the end of mass production in 2012, the “seven” was produced in 13 modifications. One of them, namely the VAZ-21077, was developed specifically for export to the UK. In this version, more expensive, alloy wheel versions were installed on it.

Knowing the basic technical parameters of a wheel rim, you can determine its compatibility with a specific car model. In addition to the diameter, you need to take into account such indicators as:

• Rim width.
• PCD – diagram for drilling mounting holes (bolt pattern).
• ET – disc ejection.
• DIA is the diameter of the central hole.

As for the bolt pattern and the central hole, everything here is traditional for the old Tolyatti models. These indicators are strictly tied to the parameters of the hub. In numerical terms, they look like this: 4x98 mm and 58.5 mm, respectively: 4 is the number of fastening points, 98 mm is the distance between the centers of opposite mounting holes, 58.5 mm is the diameter of the hole located in the center of the disk.

Rim width is measured in inches. In the VAZ-2107 this indicator is equal to the values ​​5 and 5.5. Knowing the width of the rim, you can understand how wide the tire should be. In the marking this value is written as follows: 5J and 5.5J.

Full coincidence of the central hole of the disk with the corresponding parameter of the hub helps to accurately center the disk during installation, which has a positive effect on the service life of the tires and eliminates wheel runout when driving.

Tires for VAZ 2107

The safety of the car driver and his passengers depends even more on the characteristics and condition of the car’s tires. Their choice must be approached very carefully, and in no case should you skimp.

Types of tires by seasonal use

According to seasonal use, tires are divided into:

• winter;
• summer;
• all-season.

The first ones are made of soft rubber and have a special tread. At the same time, each manufacturer tries to increase the tread area, because the larger it is, the better the tire will perform on winter roads.

The larger the tread area, the better the tire performs on slippery roads.

Summer tires are rougher, and their tread pattern is designed more for better grip on wet surfaces and drainage of water from the plane of contact between the tire and the road.

Summer tire tread is designed for wet grip

All-season tires are a generalized version of the first two types. If the “all-season” tire is really of high quality, then in winter it copes with its duties normally, but in the summer it is significantly inferior to summer tires in terms of the quality of grip on wet surfaces.

High-quality all-season tires do a good job in winter

VAZ 2107 tire parameters

Like wheels, car tires have their own parameters. These include:

• profile width (the width of the tire itself, measured in millimeters);
• height (expressed as a percentage of the profile height to the width, measured as a percentage);
• landing diameter (determines the inner diameter of the tire, measured in inches);
• load capacity (indicates the maximum load per tire, measured in kgf);
• permissible speed value (indicates the estimated maximum permissible speed, measured in km/h).

VAZ 2107 leaves the assembly line of the plant shod with thirteen-inch radial tires with a profile width of 175 or 165 mm and a height of 70%. Standard tires are designed for 190 km/h and a load on one wheel not exceeding 470 kgf.

Tires, like wheels, have their own parameters

It is impossible not to mention the tire pressure, because the vehicle’s cross-country ability, its driving performance, and fuel consumption depend on it. The manufacturer of the VAZ 2107 recommends observing the following pressure indicators.

Table: recommended tire pressure for VAZ 2107

The choice between beauty and functionality of wheels should be based on how you use the car. If it is intended for city car rides, or participates in exhibitions of tuned cars, festive motorcades, then alloy wheels and low-profile tires are an ideal option. If the car is used daily in our off-road conditions for work, then it is better to install “stamping” on it with standard tires.

What tire sizes does the manufacturer recommend to install?

Tires for a car are a kind of “part” that is available in a large assortment, so when choosing, some difficulties may arise. Taking into account the manufacturer’s recommendations when choosing one option or another is an opportunity to avoid difficulties and obtain the appropriate ease of use.

The VAZ 2107 car is a multifunctional vehicle that is suitable for country trips, for driving around the city, for transporting large luggage (within the capabilities of a passenger car), and so on. And therefore, tires must be as strong, reliable and wear-resistant as possible to prevent inconvenience and danger.

According to manufacturers, the best option is considered to be 175/70R13 82T tires, since the ratio of the width of the tire profile to its height is an opportunity to get comfortable driving without disturbing the balance of the car.

The key feature of VAZ 2107 cars is that only 13 radius is ideal here, that is, the standard option that presents the car from its best side in terms of decorative and technical design. R14 and R15 are already non-standard sizes, so they slightly change the axis of the car, raising the body and “opening” the clearance between the bumper and the road surface.
