| A - | Braking behaviour on wet surfaces |
| 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. |
| An improvement in one quality implies a decrease in an another quality. |
| Improved braking performance on wet surfaces -A- leads to a decrease in the driving comfort -B-, the rolling resistance -G- and the useful life -F- of the tyre. |
| The useful life of passenger vehicle tyres does not only depend upon the mixture used and the construction of the tyre. Conditions of use, combined with vehicle characteristics and driving styles result in major differences concerning the length of tyre life. |
| Modern automobiles with appropriate specifications enable driving geared towards both savings and tyre conservation as well as towards a more sporty style. The useful life of a tyre ranges from 5,000 to 40,000 km or more. |
Note | Driving style is the determining factor in the useful life of tyres. |
