4.1.1. The general information on wheels and tyres

Tyres are hi-tech production which has been calculated for service conditions of modern cars.
As well as at any other hi-tech production, care, leaving and service here too is necessary. Only in that case it is possible to guarantee that safety, a resource and comfort of driving will be provided throughout all service life of the tyre.
Tyres strongly depend on constantly developing process. At the expense of modern designs, "know-how" and constant quality assurance high-quality tyres are made. All admitted Audi tyres were checked by department of technical development and at cooperation with manufacturers of tyres paid off for corresponding type of the car.
Therefore we recommend to mount always at replacement of tyres admitted and recommended шинные products.
Safety of the car has the highest importance. Considering various service conditions, as for example:
– Various ranges of speeds;
– Winter and summer operation;
– A crude or dry road covering;
– The optimum compromise for traffic safety should be found.
During operation and in due course each tyre is exposed to many various loadings. Therefore it is important, that basic conditions for optimum operation of tyres have been satisfied.
Correct adjustment of corners of installation of wheels is one of the major conditions to reach optimum service life of the tyre. Therefore corners of installation of wheels by all means should be in the ordered range of the admission.

THE NOTE
The reasons of damages of tyres and claims can be different. Therefore it is very important to distinguish that became the reason of the claim of the tyre or other details.
With normal deterioration of the tyre its performance data vary. There can be noise from качения and неплавность a course. These phenomena are not considered as defects of tyres, and are accompanying deterioration. They can be eliminated purposeful measures, at least partially. In certain cases to eliminate movement noise on 100 % it will not be possible.
