Volkswagen Polo Service & Repair Manual: Winter Tires with Speed Symbol V
| Table. Refer to
→ Anchor. |
| The tire industry delivers winter tires with V-rating also.
These tires can be applied up to the maximum permissible speed vmax
= 240 km/h (149.13 mph) only under certain conditions. |
| Vehicles that require V-tires according to vehicle
registration, can be driven with V winter tires without
limitations up to speed rating “v”max
= 240 km/h (149.13 mph). |
| Vehicles with W-, Y- or ZR-tires: |
| Vehicles that require W, Y, or ZR tires according to vehicle
registration, cannot be driven with V winter tires up to “v”max
= 240 km/h (149.13 mph) under certain conditions. |
| V summer tires and V winter tires without special
designation guarantee 100% of the load capacity indicated by
their Load Index (“LI”) only up to a speed of 210 km/h (130.48
mph). |
| Speeds above 210 km/h (130.48 mph) are only possible if the
maximum load capacity of the tire is not exceeded. The load
capacity of the tire decreases as the speed increases. |
| The maximum permissible axle load and the attainable maximum
speed of certain vehicles are so high that the load capacity of
V tires is not sufficient for speeds above 240 km/h (149.13
mph). |
| Example: Tires 205/55 R 16 91V |
| The Load index (LI) 91 for this tire indicates a load
capacity of 615 kg (1355.84 lbs) per tire up to 210 km/h (130.48
mph). |
| At 240 km/h (130.48 mph), the load capacity of this tire is
reduced to only 560 kg (1234.58 lbs). For this reason, the axle
load can only be maximum 1,120 kg (2469.17 lbs). |
| The vehicle has an additional axle load of 1,150 kg (2535.31
lbs) and an attainable maximum speed of 232 km/h (144.15 mph).
This vehicle can be driven with V winter tires up to a speed of
230 km/h (142.91 mph). |
| This Applies to All V Winter Tires That Do Not Have a
Special Designation. |
| Winter tires identified with Extra Load XL. Refer to
→ Chapter „Tires, Reinforced, Extra Load“ |
| Permission Stipulations in Germany |
| Only when using winter tires is it permitted that the
highest speed attainable by the vehicle lies above the highest
speed of winter tires specified by the speed rating. |
| In this case, a warning sign in the view of the driver must
be applied with the following content: |

Tires, Reinforced, Extra Load
Some time ago, the designation “Reinforced” was replaced
with the designation “Extra Load” by some tire manufacturers. In
countries outside Europe, this designation has been conventional
for some time. There are no technical differences.
