Winter Tyres; Snow Chains - Volvo XC90 Owner's Manual

Winter tyres

Winter tyres are adapted for winter road con-
ditions.
Volvo recommends winter tyres with particu-
lar dimensions. Tyre dimensions are depend-
ent on engine variant. When driving on winter
tyres, the correct type of tyres must be fitted
to all four wheels.
NOTE
Contact a Volvo dealer for advice about
which wheel rim and type of tyre are most
suitable.
Tips for changing to winter tyres
When summer and winter wheels are
changed, mark which side of the car they were
mounted on, for example L for left and R for
right.
Studded tyres
Studded winter tyres should be run in gently
for 500-1000 km (300-600 miles), 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 mm
(0.15 inches).

WHEELS AND TYRES

Snow chains

Use of snow chains and/or winter tyres can
help to improve the traction in winter condi-
tions.
Volvo recommends that snow chains are not
used on wheel dimensions greater than
19 inches
WARNING
Use Volvo genuine snow chains or equiva-
lent chains designed for the car model, and
tyre and rim dimensions. Only single-sided
snow chains are permitted.
In the event of uncertainty about the show
chain, Volvo recommends that an author-
ised Volvo workshop should be contacted.
The wrong snow chains may cause serious
damage to the car and lead to an accident.
