| Requirements to be met by tyres |
| A - | Wet braking properties |
| The pie chart illustrates to what extent the tyre meets the various requirements. The tyre in this example (with its specific structure and rubber composition) would meet the requirements listed above (A to H) to the extent indicated by the size of the segments of the pie. |
| Improving performance in one segment would result in poorer performance in the other segments. |
| An improvement in wet braking properties -A- leads to a reduction in driving comfort -B-, rolling resistance -G- and life expectancy -F-. |
| The life expectancy of a car tyre depends not only on the rubber composition and design of the tyre. The conditions of operation, the type of vehicle and the style of driving also have a significant influence on its mileage performance. |
| Modern vehicles enable comfortable and economic driving, but also a more "sporty" driving style. Mileage performance of the tyres can vary from approx. 5,000 to 40,000 kilometres or more. |
Note | The driving style is the most important influencing factor as regards the service life of a tyre. |
