06 Wheels and tyres
General
The original jack should only be used for
changing to the spare wheel. The jack's thread
must always be well greased.
Tools - returning into place
The tools and jack* must be returned to their
correct places after use. The jack needs to be
cranked together to the correct position in
order to have space.
The foam block and spare wheel are replaced
in the reverse order to taking out.
Note that there is an arrow on the upper foam
block. It must point forwards in the car.
IMPORTANT
The tools and jack* must be stored in the
intended location in the car's cargo area
when not in use.

Winter tyres
Volvo recommends winter tyres with particular
dimensions. Tyre dimensions are dependent
on engine variant. When driving on winter tyres,

the correct type of tyres must be fitted to all
four wheels.
NOTE
Volvo recommends that you consult a Volvo
dealer about which wheel 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 tyres. This gives the tyre, and especially 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 there-
fore recommends not to drive on winter tyres
that have a tread depth of less than 4 millime-
tres.
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.
WARNING
Use Volvo genuine snow chains or equiva-
lent chains designed for the car model, and
tyre and rim dimensions. In the event of
uncertainty Volvo recommends that you
consult an authorised Volvo workshop. The
wrong snow chains may cause serious
damage to your car and lead to an accident.

The car has whole vehicle approval. This

tyres are approved. For the permissible com-
binations, see page 311
