For cars of different classes, it is customary to use different types of car tires. By performance, tires are chamber and tubeless. By design - radial and diagonal. Tires are divided into five types: summer, winter, all-weather, universal, all-terrain.
- Summer is suitable for use at positive temperatures. Provide good traction. On wet primers, this type of tire is not applicable.
- Winter - used in the winter. On snowy tracks. When the road is icy and the grip coefficient is low. It is possible to install special studs on such tires.
- All season - a combined version of the tire. Allows you to use them all year round. Characteristics are usually worse than the summer and winter options.
- Universal - are used both on unpaved and on highway roads. Installed on off-road vehicles mainly.
- Off-road terrain - suitable for SUVs when you have to drive mostly off-road. Long-term use on the track leads to rapid tire wear.
Tire marking
How are marked car tires ? A code consisting of letters and numbers breaks through from the side. It looks something like this - 195/45 R 16 91T. The first part before the slash (195) denotes the size of the cross section of the tire at its widest point. (45) is the ratio of tire height to tire width. R- designation of the tire design (radial). (16) is the inner diameter of the tire. 91- tire load factor. T is the speed index. Speed ββindex indicates optimal ride speed. It is undesirable to drive at a speed below the index - this affects the performance of the car, excessive speed affects the ride comfort. Winter ones differ from summer ones by marking M + S or M&S. Near the tire size may be marked "XL". It denotes an excess capacity of 4 units. This type is used on high-speed cars more and more often due to the increase in the weight of high-speed cars.
Tire operation.
When using tires, it is recommended that the correct pressure parameters be observed. The data for this parameter is located inside the glove compartment, or in the passport with the main characteristics of the car. If not, then contact a tire fitting - they will definitely tell you there.
Pay attention to the date of manufacture of the tire. On the side of the tire there is a four-digit code. The first two digits indicate the week of the year, the last two-year.
Washing tires must be done with special detergents - they have instructions on how to do this.
Tires must be used strictly for their intended purpose. Adjustment, selection and balancing should be carried out in points of mounting. When selecting tire tires for wheels, you must use the standards of ISO 5775 / ERTO. To ensure uniform wear, the drive and driven wheels should be changed. This can be done in 10 thousand km. run.
