Wi nt er tyres 3
See page 214 for restrictions.
Winter tyres (M + S tyres) improve safety at
extre mely low outside temperatures and
should therefore be fitted on all wheels.
The design of summer tyres means they
have lim ited qualities for winter driving.
If the m aximum p ermissible speed for the
winter tyres is less than that of the vehicle,
a notice indicating the maximum
permissible speed for the tyres must be
affixed within the driver's field of vision 3
1)
.
If you use the spare wheel when it is fitted
with a summer tyre; the vehicle's
driveability may be affected, especially on
slippery road surfaces. Obtain a
replacement for the faulty tyre as soon as
possible, and have the wheel balanced
and fitted to the vehicle.
Ensure that winter tyres are inflated to the
correct pressure specified by the tyre
manufacturer.
Wheel trims 3
If the wheel trims and tyres used are not
Vauxhall-app roved, make sure that the
tyres do not have a beaded edge -
see page 145.

Tyre chains 3
See page 214 for restrictions.
Tyre chains must not be used on the
temporary spare wheel. If you need to use
tyre chains after suffering a flat front tyre,
fit the temporary spare wheel on the rear
axle and transfer one of the rear wheels to
the front axle.
