Tire and wheel sizes, or how to understand the markings. Tire and wheel sizes, or how to understand the markings Sports wheels on a VAZ 2107

The choice of wheels for the VAZ 2107 has always been a subject of dispute among car owners. Stamped wheels are cheap, durable, unpretentious and available at any auto store. But it's worth trying to improve appearance cars, the first thing you want to do is install cast or other light alloy disks on VAZ 2107 .

Therefore, the issue of choosing disks is worthy of detailed consideration.

Wheels for VAZ 2107

Wheels, light alloy (cast, forged, prefabricated) or stamped, perform the same functions:

  • transmission of torque to the tires of the drive wheels;
  • ensuring uniform tire compaction around the circumference;
  • ensuring structural rigidity and correct placement of tires in the suspension.

The “classics” use 13-inch light-alloy and stamped wheels with four mounting bolts. 14-inch wheels can be installed as tuning.

Advantages of stamped discs:

The disadvantage of stamped discs is their heavy weight. The greater the unsprung mass, the faster the suspension collapses and the worse the handling on a bad road. In this regard, stamped wheels are much inferior to alloy wheels. The second drawback is their susceptibility to corrosion, which is why they need to be periodically cleaned and tinted.

Advantages alloy wheels:


Disadvantages of light alloys disks on VAZ 2107 :

  • A brittle material that does not bend, but breaks when subjected to a strong impact. If the disk does not split during a strong impact, it still does not bend. Therefore, if the tires on light-alloy wheels fall into a hole, they have a much higher chance of being damaged.
  • Shorter service life than stamped steel discs.
  • High price and attractive to thieves.

The high price of alloy wheels makes it necessary to take a responsible approach to their selection.

Types of alloy wheels

According to the production method, alloy wheels are divided into three types:

  • Cast - made by casting an alloy on an aluminum or magnesium base. The last option is more expensive. Physical characteristics alloy wheels vary depending on the alloy used. Accordingly, the price differs. The weight of alloy wheels is one third less than that of steel wheels. They look better, but the high fragility of the material often causes chips when hitting the edge of a large hole.

  • Forged ones differ from cast ones in production technology. Hot stamping allows the part to be lighter and stronger than casting. Also, such discs are less fragile, which increases their durability. The impact force to deform a forged disk is much greater than for a steel one. Therefore, during strong impacts, more loads are placed on the car’s suspension.

  • Prefabricated, assembled from three parts using bolts. Parts of the assembly disk are manufactured using different technologies. For example, the rim is forged, the disc is cast. This approach reduces the weight of the disk and increases maintainability. Prefabricated discs can be 2-3 times lighter than cast ones. When choosing a prefabricated disk, you should pay attention to the material of the bolts. They must be titanium. Steel bolts are susceptible to corrosion, which deteriorates the appearance and parameters of the disk.

Selection of alloy wheels

Wheels on the VAZ 2107 must correspond to the primary use of the vehicle. Low profile wheels are not suitable for driving on bad roads; if you need good handling at high speed, a high profile will not be the best choice.

The main thing is that the geometric dimensions of the disks correspond to the parameters of the car.

  • The standard VAZ classic wheel size is 13 inches. Alloy wheels can be installed on 13, 14 and 15 inches. But it should be noted that with a larger disc diameter, a lower tire profile should be used. Otherwise, the wheel will rub or will not fit into the wheel arch at all. Please note. That low-profile tires will be especially easy to damage when hitting a pothole in the asphalt.

  • Rims that are too wide (with an offset of more than 30 mm) will provide better traction, but the edges of the tires that constantly protrude due to the mudguards will cause severe contamination of the sides of the car. Also wide wheel may hit the fender liners.

  • Standard VAZ wheels have four holes for mounting bolts. The diameter of the circle on which they are placed is 98 mm. In other words, the distance between a pair of diametrically opposite holes is 98 mm.
  • The diameter of the holes is 12.5 mm. This important parameter, since the bolts will dangle in large holes, but they will not fit into smaller ones.
  • The diameter of the internal hole of the disk corresponds to the diameter of the hub - 58.5 mm. It is with its help, and not with bolts, that the disk is centered. Therefore, discs with a smaller hole will not fit on the car, while those with a larger hole will require the installation of an additional centering ring.

When choosing optimal size rims, you can use the selection service, which is available on many websites of online stores of tires and rims.

Installation of alloy wheels on a VAZ 2107

Alloy wheels are installed in the same way as stamped ones. Difficulties may arise if the diameter or offset of the disc is very different from the standard one. In this case, you will have to change the form wheel arches and fenders so that the wheel does not rub when turning or while driving. Such modifications are very labor-intensive and expensive, so you should think twice before deciding to install disks non-standard sizes for VAZ 2107.

In this article, we will try to figure out which wheels should be installed on a VAZ 2107. We will look at the markings, which indicate what dimensions a particular wheel or tire has. Based on the information given here, everyone will be able to independently select a set of wheels for their “seven”.

Factory parameters of "seven" rims

Automotive concern "AvtoVAZ" installs VAZ 2107 on cars steel wheels, which are designed for mounting tubeless tires. Factory wheels are marked 5Jxl3H2 ET 29. Let's try to figure out what this means.
The number “5” is the width of the rim of the disc. Unit of measurement - inch
Article "J" is symbol special profile disc rim
The number “13” is the fitting diameter of the wheel rim for the tire. The unit of measurement is inch.
Combination “H2” - this means that on the rim rim There are two ring lugs that are designed to mount a tubeless tire
Article number “ET” is a symbol for the size of the wheel rim offset
The number “29” is the value of the wheel rim offset size. Unit of measurement – ​​millimeters

Factory parameters of "seven" tires

Leaving the factory, VAZ 2107 cars are equipped with tubeless tires, which are marked 175/70R13 82T. Let's now look at what this means.
The number “175” is the width of the tire profile. Unit of measurement – ​​millimeters
The number “70” is the ratio of the height of the tire profile to the width of the tire profile. Unit of measurement - percentage
The "R" part number is the accepted designation for a radial tire.
The number “13” is the diameter of the tire. Unit of measurement - inch
The number “82” is the so-called load capacity index, which determines how much weight can be pressed on one such tire. In this case it is 470 kgf
Article "T" - symbol of the maximum speed for which it is designed this tire. In this case it is one hundred and ninety kilometers per hour

In addition to the standard factory set, automobile concern AvtoVAZ allows the installation of wheels marked 5/2Jxl3, which have a rim offset of twenty-five to thirty millimeters.
It is worth noting that the recommendations given by the manufacturers did not appear out of the blue. All data was checked by engineers in theory and tested in practice. And you can look at different tests of tires that were tested on the Internet. So these parameters rims and tires are ideal for a combination of several factors, including stability vehicle on the road, vehicle handling, vehicle maneuverability and vehicle safety level.
To make it more clear, let us present possible options developments if some of the recommended parameters are not observed. So, if the rim offset on a wheel is larger than the standard one, then it will cling to the brake mechanisms while driving, which can increase the braking distance. If the rim offset is less than the recommended value, then this takes the load on the hub bearings beyond the norm, and this can lead to their unexpected failure, which will lead to the unpredictability of the vehicle's trajectory, and this is a direct threat to the lives of the driver and his passengers .
Violating all other recommendations given by the manufacturer will also not lead to anything good. At best, this will increase the wear of parts of various components, and at worst, it will seriously reduce and so not the most best level safety of the VAZ 2107 car.

How to choose the correct tire size based on the manufacturer's recommendations

The manufacturing plant installs steel wheels on the 2107 car, designed for tubeless tires measuring 13 inches. The tires on the VAZ 2107 can be installed in different sizes: 5JxI3H2 ET 29 or 5’/2JxI3 with a rim offset of 25-30 cm.

When recommending choosing one or another size of VAZ 2107 tires, the manufacturer takes into account the conditions for ensuring maximum cross-country ability, stability, safety and controllability of this model. For example, if you install wheels with a large offset, they can hit the elements brake system, well, installing smaller wheels will significantly increase the load on the hub bearings, which in turn will cause unpredictable behavior of the “seven” when emergency braking or in case of failure of the brake system circuit.

High-profile tires on the VAZ 2107 will contribute to touching body parts at maximum suspension travel, but installation wide tires will lead to their friction against the side members of the car or the wing in sharp turns.

If you install tires with a lower load index than required by the manufacturer, such a wheel may burst with maximum load when hitting an obstacle, and if you install tires with a low speed index, then high speeds it may collapse.

In addition to the fact that you need to choose the right size of VAZ 2107 tires, you also need to take into account their seasonality. All types of tires are usually divided into three types: all-season, summer and winter. If a car owner uses the car all year round, and winter is always snowy, then, of course, it is better to buy two sets of tires: summer and winter. Winter tires on the VAZ 2107 are made from soft rubber, and their tread has wavy narrow sipes (slots). Such tires do not turn to stone at sub-zero temperatures and cling much better to rough road surfaces. You can also identify winter tires by the inscriptions MS or M+S on the sidewall; there may also be a “snowflake” pictogram.

The possibility of using studded tires on the “Seven” in winter depends on the specific driving conditions. But it is necessary to take into account that studs are used only to improve the grip of the wheel on hard surfaces - compacted snow or ice. In other situations, studs simply do not work, and on asphalt surfaces they even worsen the grip of the wheel on the road.

If you use winter tires on a VAZ 2107 in the summer, this will lead to their intensive wear. But all-season tires can be used all year round. In terms of their performance, such tires behave quite satisfactorily in all conditions, but in winter they are inferior in their technical performance. winter tires, and in the summer - summer.

As for the rubber tread pattern, it does not play a significant role, since it is not regulated by the manufacturer’s requirements and can be either directional or universal. If the pattern is directional, then there is an arrow on the sidewall of the tire indicating the direction of rotation of the wheel.

When choosing rims and tires for the VAZ 2107, you should take into account the parameters provided by the factory and understand the accepted markings of tires and rims. Knowing these parameters, you can independently choose the appropriate set of wheels for the VAZ 2107.

Parameters of VAZ 2107 wheels

On the factory conveyor, the “seven” was equipped with stamped steel disks under tubeless tires. Disc marking – 5Jx13H2 ET29. Here's what these numbers and letters mean:

  • “5” – disk rim width in inches;
  • the letter “J” denotes a special disk profile;
  • “13” is a value in inches characterizing the mounting diameter of the wheel rim on which the tire is mounted;
  • “H2” – the number of “humps” on the wheel rim (“hump” is a ring-shaped protrusion used when installing tubeless tires on a wheel);
  • the letters “ET” mark the offset of the wheel rim;
  • “29” is the amount of rim offset in millimeters.

Wider wheels than those provided by the manufacturer are undesirable for use on the VAZ 2107. Wide rims and corresponding tires, at best, will protrude beyond the size of the wheel arch liners, which will lead to intense contamination of the side parts of the car. In the worst case, the wheels and tires will rub against body elements when turning. Wheels with a large protrusion can also interfere with the brakes, which can lead to an accident. A smaller rim protrusion is also harmful - in this case, the load on the hub bearing increases, which leads to its premature failure and even jamming.

Parameters of standard tires VAZ 2107

Standard tires on the VAZ 2107 are marked 175/70R13 82T or 165/70R13 82T. These letters and numbers are deciphered as follows:

  • “175” (“165”) – width of the tire profile in millimeters;
  • “70” – ratio of profile height and tire width in percentage;
  • “R” – designation of a radial tire;
  • The number “13” means that the tire diameter is 13 inches;
  • The index “82” indicates the tire’s load capacity, which is 470 kg;
  • “T” – marking indicating maximum speed 190 km/h.

Installing tires with a lower profile will increase the likelihood of wheel damage when hitting a pothole. Wheels with a higher profile may not fit in the wheel arch and may rub on bumps.

It is worth remembering that non-standard profile height changes the wheel circumference and affects the accuracy of the speedometer readings.

Choice of tires by season

Tires for VAZ 2107, depending on performance characteristics, divided into summer, winter and all-season.
Summer tires are more rigid due to their lower rubber content. Due to this, they are more wear-resistant, but low temperatures their grip on the road deteriorates sharply. Therefore, at temperatures below 7 degrees, even on a clean asphalt surface, use summer tires undesirable. Winter tires remains soft even in severe frost, providing reliable grip on the road surface. However, when used in warm weather, especially in the summer heat, winter tires soften too much, which leads to poor traction and too much rapid wear tires.

Winter tires on the VAZ 2107 differ from summer tires in their tread pattern. If you do not take into account studded tires, the difference from summer tires is visible at first glance, winter tires have a deeper tread with many slots (sipes) that provide better grip on ice or snow crust. Tread lugs winter tires have a much smaller area compared to summer ones.

All-season tires are universal. They are able to provide sufficient traction in winter and are not subject to too much wear in the summer heat. However, like everything unspecialized, all-season tires inferior to summer and winter in the corresponding seasons. Its grip on snow and ice is worse than that of winter, and it is too soft and wears out too quickly in the ball compared to summer.

Winter tires on a VAZ are necessarily marked “M&S”, “M+S”, “Mud+Snow” or “Winter”. The letters “MS” (Mud+Snow) mean that the tires are suitable for driving not only on ice and snow, but also on mud. This is exactly what studded tires are, the studs of which allow you to feel confident on a muddy country road. Studless tires can also cope well with mud if there are lugs.
