At cars with forward a drive as a result of bigger load of forward tires wear of a protector comes earlier, than at tires of a back axis.

For equalizing of service life of all 4 tires of the car it is recommended to rearrange forward wheels with tires on a back axis and on the contrary.

At tires with the directed protector watch that they were not overturned.

The more long the tire is maintained on a certain wheel of the car, the more it is leveled, therefore shift of wheels is recommended to be carried out through short intervals of run, for example, each 5000 km.

Diagonal shift is possible only at tires without the directed protector. This type of shift is especially justifiable at wear of a protector in the form of a path of a sawtooth form

If wear of a protector in the form of a path of a sawtooth form progresses and the protector is worn-out more than for 50 %, this type of shift will give only small increase in run and practically is not justifiable. Elasticity of blocks of a protector worsens and sawtooth wear ceases to progress.
