Tyres - speed ratings
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
tyre (p. 321)

, where a lower speed rating
may be used. If such a tyre is chosen, the car
must not be driven faster than the speed rat-
ing of the tyre (for example, class Q can be
driven at a maximum of 160 km/h). Traffic
regulations determine how fast a car can be
driven, not the speed rating of the tyres.
NOTE
The maximum permitted speed is speci-
fied in the table.
Q 160 km/h (used only on winter tyres)
T 190 km/h
H 210 km/h
V 240 km/h
W 270 km/h
Y 300 km/h
WARNING
The car must be fitted with tyres which
have the same or a higher load index
(p. 319) (LI) and speed rating (SS) than
specified. If a tyre with too low a load
index or speed rating is used, it may over-
heat.

Wheel bolts
Wheel bolts are used to fasten the wheels at
the hubs and are available in different ver-
sions.
IMPORTANT
The wheel bolts must be tightened to 140
Nm. Overtightening can damage the nuts
and the bolts.
Only use rims that are tested and approved
by Volvo and which are Volvo genuine acces-
sories. Check the torque with a torque
wrench.
Locking wheel bolts*
Locking wheel bolts* can be used on both
aluminium and steel rims. Under the cargo
area floor there is space for the sleeve for the
lockable wheel bolts.
