Tires and pressure check in tires


Tires are the unique parts of the car which constantly are in contact to the road and even a total contact surface of all tires the small. Therefore it is necessary to carry out regularly careful check of tires as both own safety and safety of other participants in traffic in big degree depends on a condition of tires.

It is desirable to check pressure in tires before long trips as thus there is the maximum temperature load of tires. At movement on big distances on high speed at the lowered pressure in tires more energy is spent for tire deformation therefore it overheats and there can be an office of a layer of a profile or even a rupture of the tire. also at the lowered pressure in the tire fuel consumption raises.

Continuous check of a condition of tires will allow to find in due time intensive wear and to eliminate its reason that will allow to avoid more serious consequences.

In the presence of non-uniform wear of tires it is necessary to find the reason of it and to eliminate it.

Check tires on existence of cuts, punctures and extraneous subjects in tires. From the tire it is possible to define places of leakage of air by soapsuds.

Carefully survey internal lateral face of each tire on existence of traces of brake liquid.

Demanded pressure in tires prolongs term of its service and consequently it is necessary for checking regularly. Pressure control in tires make only on cold tires.

At replacement of wheels it is inexpedient to change the direction of rotation of the tire as their repeated extra earnings will cause the increased wear of tires.

Check of level of a deterioration of protectors of tires
Tires of wheels it is necessary not delay mechanism but to replace, if the special indexes which were below at the bottom of a protector (In) as a result of a deterioration are made even to a surface of a protector of the tire. The provision of indexes is designated by a triangular label on an onboard wall of the tire (And).

Measurement of depth of drawing of a protector of the tire
Depth of drawing of a protector of tires can be supervised by the special adaptation and at achievement of limiting wear of the tire it is necessary to replace.

Pressure check in tires
Pressure check in tires is made only on cold tires. Optimum pressure in tires increases service life of tires and operational parameters of the car.
