Wheels, tyres
See page 214 for suitable tyres a nd
restrictions.
F actory - f i tt e d tyr e s are m atch ed to th e
chassis and offer optimum driving comfort
and safety.
Changing tyre / wheel type
Note the necessary modifications before
switching to different tyres or wheels.
If wheel rims of a different type are to be
installed, the wheel nuts may also need to
be changed. We recom mend you consult a
Vauxhall Authorised Repairer.
If tyres of a different size to those fitted at
the fac tory are used (this includes winter
tyres), the electronic speedometer may
possibly need to be reprogram med, to
ensure that the speed displayed is correct.
Vehicles with tyre pressure monitoring
sy ste m 3
When using winter tyres, or when switching
to different tyre sizes, sensors for the tyre
pressure monitoring sy ste m ca n be fitted at
a later date by a workshop, upon request.
Otherwise, the system would not ind ic ate
tyre pressure deviations.
Tyre pressure monitoring system -
see page 140.
Fit ting new ty res
New tyres should be fitted in pairs, or, for
preference, in sets. Make sure that both
tyres on an axle are:
z the same size,
z the same design,
z the same make,
z and have the same tread pattern.
Fit directional tyres such that they roll in the
direction of travel. The rolling direction is
indicated by a symbol (e.g . an arrow) on
the sidewall.
Tyres fitted op posing the rolling direction
(e.g. when a tyre is changed) should be
refitted as soon as possible. This is the only
way to obtain full benefit from the design
prop erties of the ty re.
Observ e le gal re quirements when
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 beaded-edge tyres, the
following procedure must be followed:
z Wheel trims and tyres that are approved
by Vauxhall for the respective vehicle
and comply with all of the relevant wheel
and tyre com bina tion re quirements must
be used.
z If the wheel trims and tyres used are not
Vauxhall-approved, the tyres must not
have a beaded edg e.
