Temporary Spare; Winter Tyres - Volvo XC90 Owner's Manual

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 141 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.
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

Temporary spare

1
The spare wheel is only intended to be used
for the short time it takes to get the ordinary
wheel replaced or repaired. Replace the
spare wheel as soon as possible with a
normal wheel. The car's handling may be
altered by the use of the spare wheel.
Never drive faster than 80 km/h with a spare
wheel on the car.
By law, it is only legal to use the spare wheel/
tyre temporarily in connection with damage to
a tyre. A wheel/tyre of this type should be
replaced with a normal wheel/tyre as soon as
possible.
Remember also that this tyre combined with
the normal tyres will affect driving character-
