Tire durability
Tire life depends mainly on the following factors:
- air pressure in tires;
- the values of nominal air pressure in summer tires are indicated on the sticker on the inside of the fuel filler cap;
- it is especially important to maintain the recommended air pressure in the tires when driving at high speeds. Therefore, the air pressure in the tires should be checked at least once a month and before every long trip;
- at the same time, do not forget to measure the air pressure in the spare wheel;
- on a reduced size emergency spare wheel, the nominal air pressure is indicated on the sidewall of the tire;
- a full-size spare tire should always maintain the nominal pressure for a fully loaded vehicle;
- Tire pressure should always be checked when tires are cold. With increased air pressure in hot tires, do not bleed air from the tire. With a significant change in load, the air pressure in the tires should be adjusted accordingly;
- on vehicles with full-size wheel covers, there are extensions instead of dust caps to improve ventilation. There is no need to unscrew these extensions when checking and adjusting the air pressure in the tires;
- Too low or too high tire pressure will shorten tire life and impair driving performance.
Warning: When driving at high speed for a long time, tires with excessively low pressure do a very large amount of lateral deformation of the tires, as a result of which the tires become very hot. This can lead to the separation of the elements of the treads of the tire and even to its rupture.
Too low tire pressure leads to increased fuel consumption. Because of this, there is an excessive burden on the environment.
Driving style
Overcoming sharp turns at high speeds, rapid acceleration and hard braking - all this increases tire wear.
Wheel balancing
The wheels of the new car are balanced. During the operation of the car, under the influence of various reasons, the balancing of the wheels can be disturbed, which can be seen by deviations in the normal operation of the steering.
The imbalance of the wheels leads to increased wear of the steering parts of the tires and the suspension of the car, therefore, if an imbalance occurs, the wheels should be re-balanced. Steering wheel vibration due to wheel imbalance occurs in a certain speed range and disappears when the speed decreases or increases. In addition, wheel balancing is necessary after fitting a new tire and after each tire repair.
Incorrect wheel alignment
Incorrect wheel alignment not only causes increased tire wear, especially one-sided wear, but also contributes to a decrease in traffic safety.
Tire wear indicators
Location of markers on the sidewall of the tire (e.g. letters "TWI" or an icon in the form of a triangle)
In the grooves of the tire tread pattern there are "tire wear indicators" 1.6 mm high located at right angles to the direction of translation of the tire. These indicators range from six to eight (depending on the manufacturer) placed at equal distances around the circumference of the tire. Tire sidewall markers (e.g. letters "TWI" or an icon in the form of a triangle) show the location of the tire wear indicators.
Warning: Intense tire wear is promoted by a sporty driving style, intense acceleration and hard braking.
Warning: Tires can be used up to a profile depth of 1.6 mm, i.e. the profile grooves must have a depth of at least 1.6 mm over the entire surface of the tire. However, for safety reasons, it is recommended to change tires at a profile depth of 2 mm.
Warning: M+S tires on snow have sufficient traction with a profile depth of at least 4 mm.
Warning: Inspect the tire for cuts and determine their depth. If cuts reach the cord, the steel cord will corrode from penetrating moisture.
Warning: Tires should be replaced at the latest when their tread is worn down to the wear indicators.
Warning: Worn tires do not provide the necessary traction, especially when driving at high speeds on wet roads. In addition, with worn tires, hydroplaning occurs much faster (loss of wet grip).
