WHEELS AND TYRES

Speed rating
Each tyre can withstand a certain maximum
speed. Tyre speed rating, SS (Speed Symbol),
must at least correspond with the car's top
speed. The table below shows the maximum per-
mitted speed for each speed rating (SS). The
only exception to these regulations is winter
tyres
2
, 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).) The top speed at which
the car can be driven depends on road condi-
tions, not the speed rating of the tyres.
The maximum permitted speed is specified in
the table.
Q
160 km/h (100 mph) (used only on win-
ter 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 lowest permitted load index (LI) and
speed rating (SS) for the tyres for each
respective engine variant are shown in the
car's registration document. If a tyre with too
low a load index or speed rating is used, it
may overheat and be damaged.
