- 5 rim width in inches;
- J symbol for rim profile;
- 13 rim seat diameter for tire in inches;
- H2 conventional designation of the shape of the rim landing shelves;
- ET is the symbol for rim offset;
- 35 rim offset in millimeters.
Note: Rim offset (ET) is the distance between the plane that divides the wheel rim in half (plane equidistant from the sides of the rim), and the mounting (fastening) plane of the wheel.
The car is equipped with tubeless tires 175/70R13 82 T, H, where:
- 175 profile width in millimeters;
- 70 ratio of profile height to its width in percent;
- R designation of radial tire;
- 13 tire seat diameter in inches;
- 82 load index (maximum permissible load on the tire is 475 kgf);
- t, H speed indices (maximum permissible speed 190 and 210 km/h respectively).

The maximum load on the tire (MAX LOAD) is duplicated in a deciphered form together with the indication of the maximum permissible pressure (MAX AT) of air in the tire.
It is also permissible to install 5½Jx13, 5Jx14, 5½Jx14 and 6Jx14 wheels on the vehicle. Wheels with a larger rim diameter must be fitted with 175/65R14 82T, Η or 185/60 R14 82T, H tyres.
When giving recommendations on the choice of certain tires, the manufacturer takes into account the conditions for ensuring maximum stability, control, cross-country ability and safety of the car. Thus, wheels with a large offset can touch the brake mechanism parts, and those with a smaller offset increase the load on the hub bearings and can lead to unpredictable behavior of the car during emergency braking or in the event of failure of one of the brake system circuits. High-profile tires can touch the body parts at maximum suspension travel, and wide ones can rub against the car's side members or its fenders at large turning angles. A tire with a lower load index can burst under a maximally loaded car, and underestimating the speed index is fraught with destruction of the tire when driving at high speed.
Tires that can be installed on a car are divided into three types: summer, winter and all-season. If the car is used all year round and the winter is snowy, it is better to have two sets of wheels: with winter and summer tires. Winter tires are made of softer rubber, which allows them not to "harden" at sub-zero temperatures, and narrow wavy cuts - lamellas - are made on the tread. This allows the tire to better cling to the roughness of the surface. The inscription "M + S" or "MS" can be applied to the sidewalls of winter tires. The possibility of using studded tires in winter depends on the specific operating conditions of the car. It should be taken into account that studs are designed to improve the grip of the tire only on a slippery hard surface, such as ice or packed snow. In other cases, studs are useless, and on asphalt they even slightly worsen the grip of the tire on the road.
Using a winter tire in summer results in intensive wear.
All-season tires can be used all year round. They are distinguished from other tires by the inscription "ALL SEASON" or "TOUS TERRAIN" on the sidewall. According to their performance, they behave satisfactorily in various weather conditions, but in summer they are inferior to summer tires in terms of technical performance, and in winter - to winter tires.
The tread pattern can be universal or directional, and is not regulated by the manufacturer's requirements. With a directional tread pattern, the inscription "ROTATION" and an arrow indicating the direction of rotation of the wheel when the car is moving forward are applied to the sidewall of the tire. A special case of a directional pattern is asymmetrical. In this case, the inscription "OUTSIDE" is applied to the sidewall, which must be on the outside during installation.
