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. Minimum speed rat-
ing is indicated in the speed rating table
below. The only exception to these regula-
tions is the winter tyre (p. 333)
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 maxi-
mum of 160 km/h). Traffic regulations deter-
mine 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

WARNING
The car must be fitted with tyres which
have the same or a higher load index
(p. 331) (LI) and speed rating (SS) than
specified. If a tyre with too low a load

, where a
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.
