Winter tyres with speed symbol „V“
Table → Chapter
The tyre-manufacturing industry also supplies winter tyres with a V speed rating. However, these tyres may be driven up to the maximum permissible speed vmax = 240 km/h only under certain conditions.
Vehicles with V speed rating tyres entered in documents
Vehicles which according to the vehicle documents require V speed rating tyres may be driven without restriction up to a maximum permissible speed „v“max = 240 km/h when winter tyres rated V are fitted.
Vehicles with W, Y or ZR speed rating tyres entered in documents
Vehicles which according to the vehicle documents require W, Y or ZR speed rating tyres may not be driven up to „v“max = 240 km/h under certain conditions when these tyres are fitted.
Reason
V-rated summer tyres and V-rated winter tyres without special markings have 100 % of their maximum load capacity (as specified by load index „LI“) only at speeds of up to 210 km/h.
With V-rated winter tyres, speeds above 210 km/h are only possible if the maximum load capacity of the tyres is not exceeded. The maximum load capacity of the tyres decreases as the speed increases.
The maximum permissible axle load and the maximum speed of some Audi vehicles are so high that the load capacity of the V-rated tyres is not sufficient for speeds of up to 240 km/h.
Example: 205/55 R 16 91V tyres
The load index (LI) 91 certifies that this tyre has a load capacity of 615 kg per tyre at up to 210 km/h.
At 240 km/h this tyre can only carry a load of 560 kg; therefore the maximum axle load is only 1120 kg.
The vehicle has a permissible axle load of 1150 kg and a maximum speed of 232 km/h; this vehicle may be driven at a maximum speed of 230 km/h on V winter tyres.
This applies to all V winter tyres without special markings.
Winter tyres with the designation Extra Load XL → Chapter
Registration regulations in the Federal Republic of Germany
It is only permissible that the top speed that the vehicle can reach is above the maximum speed specified by the speed symbol when winter tyres are fitted.
In this instance, a label indicating the following must be attached in the driver's field of vision:
   
Caution: winter tyres!
Maximum permissible speed ... km/h
