TIRE MARKING

When selecting a new set of car wheels you should pay attention to the marking on the sidewall of the tire, deciphering which will help you to choose the right tire for your car. This is important information not only about the size of the tire, but also about its technical characteristics. If you can not understand the symbols yourself, experienced consultants will always help. Tire category. It defines one of two categories - LT - for a truck, P - for a car.

Your car already has 235 65 r17 tires  installed, then we recommend using this tire size in the future.

Tire width.

The distance from one edge of the tire to the other in millimeters. The diameter of the wheel. The inside diameter of the tire, i.e., the diameter of the rim in inches. The ratio of tire section height to tire width. The height of a tire at a given width. Load index. Indicates the maximum load a tire can carry. Speed index. Identifies the maximum permissible speed of a vehicle for a given tire.

Tire construction.

R" represents radial tire construction, with the tire cords running without overlap from one bead to the other. B (Bias) is a diagonal tire construction, in which the cords are arranged at an angle of 30-40° to the radial direction of the tire, and in separate layers they overlap each other.

Wear rate is a relative value, because in addition to the composition of the rubber, wear can be affected by factors such as the nature of the driver, the quality of the road surface, asphalt temperature, etc. The wear factor is represented by a number from 60 to 620 with an interval of 20 units. The higher the value of the coefficient, the higher the mileage the tire should have.

Often sports tires have a low wear coefficient, as the tires are designed for high speed, but not continuous driving TRACTION coefficient, which may have values A, B, C. Tires with a coefficient A have the best traction with the road surface.
