Wheels and tyres

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 151 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 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

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. This 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 equiv-

alent chains designed for the car model,

and tyre and rim dimensions. Consult an

authorised Volvo workshop.
