Limited maximum speed for winter tires with speed index V

Restricted maximum design speed for winter tires with "V" identification (speed index)

For V tires the maximum tire load capacity according to ETRTO (European Tire and Rim Technical Organization) standard is only given up to 210 km/h.

As speed increases beyond 210 km/h the permissible tire load capacity is reduced by the so-called load allowance (1.5 % per 5 km/h) up to 91 % at 240 km/h.

This may mean that the vehicle cannot be operated without restriction up to 240 km/h. The maximum permissible speed is dependent on the tire's load index and the vehicle's permissible axle load (motor vehicle registration certificate Section I Sub-section 7 and 8).

This can be determined on a vehicle-specific basis with the aid of the corresponding load allowance table for the V winter tires.

A corresponding M & S maximum speed label is to be attached in the driver's field of vision.

The tire pressure (See fuel filler door for specification) is to be increased as follows:

 Up to 220 km/h + 4 %

 Up to 225 km/h + 6 %

 Up to 230 km/h + 8 %

 Up to 235 km/h + 10 %

 Up to 240 km/h + 12 %

The maximum tire pressure may not exceed 3.5 bar (350 kPa).
