MODEL 117, 124, 129, 164, 166, 169, 170, 171, 172, 176, 190, 197, 199, 202, 203, 204, 207, 208, 209, 210, 211, 212, 215, 216, 218, 219, 220, 221, 222, 230, 231, 246, 251, 292, 463
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 215 km/h + 2 %
- 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).
