Winter tyres

Volvo recommends winter tyres with particu-
lar dimensions. These are stated on the tyre
pressure label, see page 214. The tyre
dimensions are dependent on the engine var-
iant. 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
demands on tyres than summer conditions.
Volvo therefore recommends not to drive on
winter tyres that have a tread depth of less
than 4 millimetres.

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 discs 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
