Winter Tyres - Volvo C70 Owner's Manual

General
Tyres with tread wear indicators
Tread wear indicators are narrow treadless
bands across the width of the tread. On the
side of the tyre are the letters TWI (Tread
Wear Indicator). When only 1.6 mm of tread
remains, this band is clearly visible. Change
the tyres as soon as possible. Remember that
tyres with little tread depth provide very poor
grip in rain and snow.

Winter tyres

Volvo recommends winter tyres with
particular dimensions. These are stated on
the tyre pressure label; see page 138 for its
location. The tyre dimensions are dependent
on the engine variant. When driving on winter
tyres, these must be fitted to all four wheels.
NOTE! Ask an authorised Volvo workshop
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
especially the studs, a longer lifespan.
NOTE! The legal provisions for the use of
studded tyres vary from country to country.
Tread depth
Road conditions with ice, slush and low
temperatures place considerably higher
demands on tyres than summer conditions. It
is therefore not recommended to drive on
winter tyres that have a tread depth of less
than four millimetres.
Snow chains
Snow chains may only be used on the front
wheels.
NOTE! 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.
Wheels and tyres
IMPORTANT!
Use Volvo genuine snow chains or equiv-
alent chains designed for the car model,
and tyre and rim dimensions. Consult an
authorised Volvo workshop.
