Volkswagen Golf Service & Repair Manual: Winter tyres with speed symbol V
| The tyre industry now supplies winter tyres with speed
symbol "V". But only under certain conditions may these tyres be
used up to the maximum permitted speed vmax
= 240 km/h. |
| Vehicles requiring V tyres according to the vehicle's title
document may be driven at speeds of up to “v”max
= 240 km/h without any restrictions using winter tyres with
speed symbol V. |
| Vehicles with W, Y or ZR tyres: |
| Under certain circumstances, vehicles requiring W, Y or ZR
tyres according to the vehicle's title document may not be
driven at speeds of “v”max =
240 km/h. |
| V summer tyres and V winter tyres without special
identification have 100 % of their maximum load capacity (as
specified by their load index “LI”) only up to speeds of
210 km/h. |
| Travelling at over 210 km/h is possible with V winter tyres
only if the maximum load of the tyres is not exceeded. The load
capacity of the tyres decreases as the speed increases. |
| Some vehicles have such a high maximum gross axle weight
rating and maximum achievable speed that the load capacity of
the V tyres is not sufficient for speeds of up to 240 km/h. |
| Example: tyre 205/55 R 16 91V |
| 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 a speed of 240 km/h, this tyre can carry a load of only
560 kg, i.e. the axle load may not exceed 1120 kg. |
| The vehicle has a permitted gross axle weight rating of
1150 kg and an achievable maximum speed of 232 km/h. This
vehicle may only travel at speeds of up to 230 km/h with V
winter tyres. |
| This applies to all V winter tyres without special markings. |

| Only when winter tyres are in use may the top speed that a
vehicle can achieve be greater than the maximum speed specified
by the speed symbol of the tyre. |
| In this case, a label stating the following must be attached
at a location which is clearly visible to the driver: |
