General notes on wheels and tyres (passenger cars)
This information is intended to help you form an opinion as precise and accurate as possible in cases of tyre damage and other complaints.
In this chapter you will learn more about tyres and wheels/rims.
Tyres are high-tech products that are especially adapted to the requirements of modern vehicles.
As with all highly developed technical products, tyres require proper care, maintenance and service. This is essential to ensure safety, performance and comfort for the entire service life of the tyre.
Tyres are constantly being further developed. Quality tyres are the result of modern design methods and production processes, as well as continuous quality checks. All tyres that are recommended by VW have been tested by the technical development department and have been designed specifically for each model in collaboration with the tyre manufacturers.
We therefore recommend fitting only the recommended tyre makes when renewing tyres.
Vehicle safety is the top priority. With regard to the various operating conditions such as
l  differing speed ranges,
l  winter and summer use and
l  wet and dry roads,
the optimal compromise for vehicle safety must be found.
Every tyre is subjected to a wide range of different driving conditions over its entire service life. It is therefore important that the basic requirements for ensuring optimal tyre performance are met.
Proper adjustment of the axle geometry during wheel alignment is an important prerequisite for ensuring the maximum service life of the tyre. The wheel alignment must always be within the specified tolerance range.
Information for wheel alignment → Running gear, axles, steering; Rep. gr.44.
Tyre damage and related problems can have various causes. It is therefore very important that one determines whether the problem has been caused by the tyre or by other components.
Normal wear and tear on a tyre will alter its characteristics. Rolling noises or rough running can be the result of such wear. These are simply the symptoms of normal wear and tear and do not constitute damage in the sense of the tyre being defective. You can take measures to eliminate the symptoms at least to some degree. However, in some cases it may not be possible to eliminate tyre noise completely.
Special models
Special models are only partly represented in the tables in Appendix 2 for parts certificate. Modification of these vehicles depends on the engine capacity of the basic model.
