Operation Manual

Wheels, tyres 149
Fit direc tional tyres such that they roll in the
direction of travel. The rolling direction is
indicated by a symbol (e.g. a n arrow) on
the sidewall.
Tyres fitted opposing the rolling direction
(e.g. when a tyre is changed) should be
refitted a s soon as possible. This is the only
way to obtain full benefit from the design
properties of the tyre.
Observe legal requirements w hen
disposing of tyres.
Some brands of tyres have a beaded edge
for alloy wheels to protect against
damage. If wheel trims are used on steel
wheels with bead ed-edge tyres, the
following procedure must be followed :
z Wheel trim s and tyres that are approved
by Vauxhall for the respective vehicle
and comply with all of the relevant wheel
and tyre comb ination requirements must
be used.
z If the wheel trims and tyres used are not
Vauxhall-approved, the tyres must not
have a beaded edge.

Tyre inflation pressure
Check tyre pressures, including the spare
wheel 3, at least every 14 days and prior to
any long journey. The tyres should be
checked when cold , as warm tyres produce
inaccurate readings. Don't forget to check
the spare.
Use the v alve cap k ey 3 to make
unscrewing the valve caps easier. The key
is located on the inside of the tank flap.
Tyre pressures - see page 207.
Increased pressure resulting from tyre
warm-up must not be reduced, otherwise
the pressure may drop below the
permissible minimum when the tyres cool
down.

After having checked the tyre pressures,
securely tighten the valve caps.
Incorrect inflation pressures will impair
safety, vehicle handling, comfort and fuel
economy and will increase tyre wear.
If the pressure is too low , this can result in
considerable tyre warm-up and internal
damage, lead ing to tread separation and
even to tyre blow-out at high speeds.
Hidden tyre damage is not eliminated by
subsequently adjusting the inflation
pressure.

Incorrect tyre pressure could lead to a flat
tyre.
