Tyres - speed ratings
Each tyre can withstand a certain maximum speed and therefore belongs to a particular speed rating (SS - Speed Symbol).
Tyre speed class must at least correspond with the car's top speed. Minimum speed rating is indicated in the speed rating table below. The only exception to these regulations is the winter tyre1, where a lower speed rating may be used. If such a tyre is chosen, the car must not be driven faster than the speed rating of the tyre (for example, class Q can be driven at a maximum of 160 km/h). Traffic regulations determine how fast a car can be driven, not the speed rating of the tyres.
Note
The maximum permitted speed is specified in the table.
| Q | 160 km/h (used only on winter tyres) |
| T | 190 km/h |
| H | 210 km/h |
| V | 240 km/h |
| W | 270 km/h |
| Y | 300 km/h |
Warning
The car must be fitted with tyres which have the same or a higher load index (LI) and speed rating (SS) than specified. If a tyre with too low a load index or speed rating is used, it may overheat.
