Tyres - speed ratings

Updated 7/23/2018

Each tyre can withstand a certain maximum speed and therefore belongs to a particular speed rating (SS - Speed Symbol).

Tyre speed class must at least correspond with the car's top speed. The table below indicates the maximum permitted speed that applies for each speed rating (SS). The only exception to these regulations is the winter tyreBoth those with metal studs and those without., where a lower speed rating may be used. If such a tyre is chosen, the car must not be driven faster than the speed rating of the tyre (for example, class Q can be driven at a maximum of 160 km/h(100 mph)). Traffic regulations determine how fast a car can be driven, not the speed rating of the tyres.

Note

The maximum permitted speed is specified in the table.

Q

160 km/h (100 mph) (only used on winter tyres)

T

190 km/h (118 mph)

H

210 km/h (130 mph)

V

240 km/h (149 mph)

W

270 km/h (168 mph)

Y

300 km/h (186 mph)

Warning

The car must be fitted with tyres which have the same or a higher load index (LI) and speed rating (SS) than specified. If a tyre with too low a load index or speed rating is used, it may overheat.
