4.1.25. Shift of wheels
At cars with forward a drive as a result большей loadings on forward tyre covers deterioration of a protector comes earlier, than at tyres of a back axis.
For service life equalising of all 4 tyres of the car are recommended to rearrange forward wheels with tyres on a back axis and on the contrary.
At tyres with the directed protector watch that they have not been turned.
The longer the tyre is maintained on a certain wheel of the car, the more it is levelled, 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 tyres without the directed protector. The given kind of shift is especially justified at deterioration of a protector in the form of a path of the sawtooth form
If deterioration of a protector in the form of a path of the sawtooth form progresses also a protector is worn out more than on 50 %, the given kind of shift will give only small increase in run and practically is not justified. Elasticity of blocks of a protector worsens also sawtooth deterioration ceases to progress.
