- 5 - rim width in inches;
- J - symbol of the rim profile;
- 13 - landing diameter of the rim for the tire in inches;
- H2 - the presence of two humps on the rim (ring protrusions for installing a tubeless tire);
- ET - rim offset symbol;
- 29 - rim offset in millimeters.
Note: Rim offset (ET) is the distance between the plane dividing the wheel rim in half (plane equidistant from the rim flanges) and mating (fixing) wheel plane.
The vehicle is equipped with tubeless tires 175/70R13 82T, 165/70R13 82T or 165/80R13 80T, where:
- 175 (165) - profile width in millimeters;
- 70 (80) - the ratio of the profile height to its width in percent;
- R - designation of the radial tire;
- 13 - tire diameter in inches;
- 82 (80) - load index (the maximum allowable load on this tire is 470 (450) kgf);
- T - speed index (the maximum allowed speed for this tire is 190 km/h).
The maximum tire load is duplicated in deciphered form, along with an indication of the maximum allowable air pressure in the tire.
It is also allowed to install wheels 5½Jx13 with a rim offset of 25-30 mm on the car.
Giving recommendations in the choice of certain tires, the manufacturer proceeds from the conditions for ensuring maximum stability, handling, patency and safety of the car. So, wheels with a long reach can touch the parts of the brake mechanisms, and with a smaller one, they increase the load on the hub bearings and can lead to unpredictable behavior of the car during emergency braking or in the event of a failure of one of the brake system circuits. High-profile tires can touch body parts at maximum suspension travel, and wide tires can rub against the car's side member or fender at large turning angles.
A tire with a lower load index may burst when the maximum loaded vehicle hits an obstacle, and an underestimation of the speed index is fraught with destruction of the tire at high speed.
Tires that can be installed on a car are divided into three types: summer, winter and all-weather. If the car is operated all year round, and the winter is snowy, then it is better to have two sets of wheels: with winter and summer tires. Winter tires are made of softer rubber, and narrow wavy slots are made on the tread - sipes. This allows the tire to better cling to the roughness of the coating and not "petrify" at negative temperatures. Winter tires can be printed on the sidewalls "M+S", "MS" or icon "snowflake". The possibility of using studded tires in winter depends on the specific operating conditions of the car. Keep in mind that studs are designed to improve the tire's grip on slippery hard surfaces such as ice or packed snow. In other cases, the spikes do not work, and on asphalt they even slightly worsen the grip of the tire with the road.
The use of winter tires in the summer leads to their intensive wear.
All season tires can be used all year round. From the rest of the tires they are distinguished by the inscription "All season" or "Tous terrain" on the sidewall. In terms of their performance, they behave satisfactorily in various weather conditions, but at the same time they lose in terms of technical indicators to summer tires in summer, and in winter to winter ones.
The tread pattern can be universal or directional, and is not regulated by the manufacturer's requirements. With a directional tread pattern, the inscription is printed on the sidewall of the tire "Rotation" and/or an arrow indicating the direction of wheel rotation as the vehicle moves forward.
