Overview



Tires perceive the weight of the car, extinguish small bumps on the carriageway and transmit forces arising during acceleration, braking and cornering.
Features modern tire - size, external loads, internal pressure, and the maximum recommended speed - standardized to ensure interchangeability of tires during their operation.
Modern tires mounted on the vehicle, ensure high comfort ride, stability, manageability, security, and efficiency of the car.
Comfort is provided by the soft suspension, low noise level and smooth motion due to a slight deviation of the outer surface of the tire on the shape of a circle.
Traffic safety due to robust tire to rim fitment and good adhesion to the tire and the road surface.
Initially, new tires still do not provide sufficient adhesion to the road surface, so the first move should be 100 km at a moderate speed and very carefully - in this period, it is necessary to break in the bus. The successful implementation of this process contributes to the life of the tires.
In the operation of the bus from time to time shall be tested for strength (as a result there are punctures, cuts, tears and swellings). Regularly remove foreign bodies from the tire tread.
To avoid damage to tires and wheels, you have to slow as possible at right angles to overcome curbs or other similar obstacles.
Sometimes, tires and wheels have hidden damage. This may indicate the emergence of unusual vibrations or pull to one side. If there is a suspicion that the tire is damaged, you must immediately reduce speed. Check the tires for damage (cracking, blistering, and so on. N.). If outside do not show any damage, slowly and carefully follow to the nearest service enterprise for a thorough check the status of the tires.
If possible, avoid the tire contact with oils, greases and fuels.
Before removing the wheels need to make them relevant notes to when refitting could keep the same direction of rotation of tires.
When installing tire with directional tread pattern (which can be found on the arrow on the sidewall) is necessary to ensure the correct direction of rotation of the tire, so that is achieved the optimal behavior of the tire on the road, traction with the road, quietness, traction.
The service life of the tire largely depends on the air pressure therein.
It is particularly important to maintain the recommended tire pressure when driving at high speed. Regularly check tire pressure at least once a month and before every long trip. Do not forget to measure the pressure in the spare wheel.
The pressure should be checked on cold tires. With increased pressure in the tire can not be heated to release the air from the tire. Tyre pressure is adjusted depending on the load of the vehicle.
Too low or too high tire pressure will shorten their service and worsens road performance of the car.
With long-term driving at a high speed with an excessively low tire pressure is strongly heated, which may lead to the separation of elements treadmills tire and even break.
Too low pressure contributes to increased fuel consumption.
Overcoming the sharp turns at high speeds, sharp acceleration and braking also increase tire wear.
The deviation of the wheels from the standard values not only causes increased wear on the tires, especially unilateral deterioration, but also helps to reduce traffic safety.
