4.1.1. General information on wheels and tires

Tires are hi-tech production which was 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, the resource and comfort of driving will be provided throughout all service life of the tire.

Tires strongly depend on constantly developing process. At the expense of modern designs, production technologies and constant control of quality high-quality tires are made. All allowed Audis of the tire were checked by department of technical development and at cooperation with producers of tires paid off for the corresponding type of the car.

Therefore we recommend to mount always when replacing tires the allowed and recommended tire products.

Safety of the car has the highest importance. Considering various service conditions, such as:

– various ranges of speeds;

– winter and summer operation;

– crude or dry paving;

– compromise, optimum for traffic safety, has to be reached.

During operation and over time each tire is exposed to many various loadings. Therefore it is important that basic conditions for optimum operation of tires were satisfied.

The correct adjustment of angles of installation of wheels is one of the major conditions to reach optimum service life of the tire. Therefore the angles of installation of wheels by all means have to be in the ordered admission range.

NOTE The reasons of damages of tires and claims can be different. Therefore it is very important to distinguish that became the reason of the claim of the tire or other details. With normal wear of the tire its performance data change. There can be noise from swing and not smoothness of the course. These phenomena are not considered as defects of tires, and are accompanying wear. They can be eliminated with purposeful measures, at least partially. In certain cases it will not be possible to eliminate noise of the movement for 100%.
