Check of depth of a protector
Check of wear and damages of tires
Care of tires comes down to check of depth of a protector, pressure in tires (it is checked on cold tires), to identification of traces of abnormal wear and damages by which it is possible to determine a condition of details of a forward suspension bracket and steering.
Regularly delete the stones or sharp objects which got stuck in a protector. Periodically remove wheels and clear external and internal surfaces of a disk of dirt.
If there are doubts concerning consequences of any found damages, then address for consultation in a shinoremontny workshop. Rearrange wheels with a certain frequency. At installation of the new tire on a disk consider the following.
Width of a protector of the tire has to differ from distance between internal boards of the tire no more than on 25 mm. On radial tires width between internal boards has to be no more than 80% of tire width.
Tire height in the established state significantly influences the accuracy of indications of a speedometer, dynamics of dispersal and clearance of the car. Necessary amendments are specified by the manufacturer of tires. In the spare part speedometer reducers with the corrected transfer number are delivered.
At installation of new tires the abnormal inclination of a body when driving on the bumpy road should not be observed or at turns.
Shift of wheels
Scheme of shift of wheels
Wheels are rearranged for the purpose of increase in uniformity of wear of tires through 12000 km.
At removal of winter snow tires designate the provision of the removed wheel and the direction of thorns. Shift of wheels which tires are calculated on different loadings is not allowed and are established on forward and back axes separately.
The manufacturer recommends to install radial tires in a uniform set (5 wheels). It is allowed to install in extreme cases radial tires of an identical design on a back axis.
