When replacing a wheel or tire, be sure to replace the rubber valve with the nipple.
During the initial period of operation, new tires do not provide sufficient grip on the road surface; the first 100 km should be driven at moderate speed with special care - during this period the tires "roll in". Following these recommendations will help to increase the service life of the tires.
During operation, tires are subject to strength tests, which may result in punctures, cuts, tears and bulges. Foreign bodies should be regularly removed from the tire tread.
To avoid damage to tires and rims, drive slowly and, if possible, at right angles over curbs and other similar obstacles.
Often, tires and wheels have hidden damage. The appearance of unusual vibration or the car pulling to the side may indicate damage to the tire. In this case, you should immediately reduce speed! Check the tires for damage (cracks, swelling, etc.). If no external damage is found, drive slowly and carefully to the nearest service center for a thorough inspection of the tire condition.
Avoid contact of tires with oils, greases and fuels.
Any lost dust caps must be replaced with new caps immediately.
Before removing the wheels, they must be marked so that the original direction of rotation of the tires can be maintained when reinstalling them.
Removed wheels and tires should be stored clean and dry, preferably in a dark room. Tires not mounted on rims should be stored in an upright position.
Before removing the wheels, increase the tire pressure by 0.3–0.5 bar.
When installing tires with a directional tread pattern (they can be identified by the arrow on the side) it is necessary to ensure the correct direction of rotation of the tire, due to which optimal "behavior" of the tire on the road, traction, noiselessness, transmission of traction force, and aquaplaning will be achieved.
The service life of tires depends largely on the air pressure in them.
It is especially important to maintain the recommended tire pressure when driving at high speeds. You should check your tire pressure regularly, at least once a month and before each long trip. Don't forget to check the pressure in the spare tire as well.
The pressure should be checked on cold tires. If the pressure in warm tires is too high, the air should not be released from the tire. The tire pressure is changed according to the vehicle load.
Too low or too high tire pressure reduces their service life and impairs the vehicle's driving performance.
When driving a car for a long time at high speed, tires with excessively low pressure become very hot. This can lead to the separation of the tire tread elements and even to its rupture.
Too low pressure will result in increased fuel consumption.
Taking sharp turns at high speeds, and sudden acceleration and braking also increase tire wear.
Deviation of wheel alignment angles from standard values not only causes increased tire wear, especially one-sided wear, but also contributes to reduced driving safety.
The wheels of a new car are balanced. During the operation of the car, under the influence of various reasons, the wheel balance may be disturbed, which can be noticed by deviations in the normal operation of the steering.
Wheel imbalance leads to increased wear of steering components, tires and vehicle suspension, so the wheels should be balanced. Vibration of the steering wheel from wheel imbalance occurs in a certain speed range and disappears when the speed decreases or increases. Wheel balancing is necessary after mounting a new tire and after each tire repair.
