Rims and wheel bolts
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 alu-
minium and steel rims.
06 Maintenance and specifications
Winter tyres
Volvo recommends winter tyres with particu-
lar dimensions. These are stated on the tyre
pressure label, see page 207. The tyre di-
mensions are dependent on the engine vari-
ant. When driving on winter tyres, the correct
tyres must be fitted to all four wheels.
NOTE
Ask a Volvo dealer which rim and tyre types
are most suitable.
Studded tyres
Studded winter tyres should be run in gently
for 500-1000 km so the studs settle properly
into the tyre. This gives the tyre, and espe-
cially the studs, a longer service life.
NOTE
The legal provisions for the use of studded
tyres vary from country to country.
Tread depth
Road conditions with ice, slush and low tem-
peratures place considerably higher de-
mands on tyres than summer conditions.
Volvo therefore recommends not to drive on
winter tyres that have a tread depth of less
than 4 millimetres.
Wheels and tyres
Using snow chains
Snow chains may only be used on the front
wheels (also applies to all-wheel drive cars).
Never drive faster than 50 km/h with snow
chains. Avoid driving on bare ground as this
wears out both the snow chains and tyres.
Never use quick-fit snow chains as the space
between the brake disks and the wheels is
too small.
IMPORTANT
Use Volvo genuine snow chains or equiva-
lent chains designed for the car model, and
tyre and rim dimensions. Consult an author-
ised Volvo workshop
