| 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 one of the characteristics will have a negative effect on one of the others. |
| 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 passenger vehicle tyres does not just depend on the rubber composition and design of a tyre. The conditions for use, the vehicle-specific circumstances and driving style have a heavy influence on the service life of a tyre. |
| Modern vehicles enable comfortable and economic driving, but also a more "sporty" driving style. A tyre life of 5,000 to 40,000 km or more is possible. |
Note | The driving style is the most important influencing factor as regards the service life of a tyre. |
