Diagonal non-uniform deterioration of tyres
|Fig. 4.10. Diagonal non-uniform deterioration of tyres
Diagonal stains of non-uniform deterioration pass at an angle approximately 45 ° rather to a direction of a circle of the tyre (fig. 4.10
More often on all circle of a protector such stain one, but sometimes meet and some «shabby stains».
Such stains of deterioration meet almost exclusively on tyres неприводных wheels, especially on the back left. There are models of cars on which such deterioration of tyres, and also the models completely relieved of similar problems is often shown. The given effect amplifies a strong convergence. The values of the convergence lying at the bottom limit of the admission of ordered adjustments, improve the deterioration characteristic.
In area of the most strongly worn out diagonal stains often there is a joint of elements of the tyre.
Wheels with a positive convergence even at rectilinear movement by inertia slide with a corner of lateral withdrawal. It conducts to diagonal deformation in a zone of contact of the tyre with a road covering.
At driving with insufficiently beefy tyres such character of deterioration increases. For avoiding of similar deterioration the convergence of both back wheels should be identical, besides it is necessary watch correctness of pressure of air in tyres.
At detection of stains of non-uniform deterioration these wheels are recommended to be established on a leading axis provided that deterioration still is in an early stage. Deeper stains of non-uniform deterioration are incurable.
At the complaint to «diagonal stains of non-uniform deterioration» it is necessary check up convergence adjustment. If a convergence in norm the reason with the big degree of probability is covered in the tyre.
Tyres with diagonal stains of the non-uniform deterioration, appeared because of wrong adjustment of corners of installation of wheels, do not fall under a guarantee.
