Wheels, tyres
See page 223 for suitable tyres and
restrictions.
Factory-fitted tyres are matched to the
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 recommend you consult
an Opel Partner.
If tyres of a different size to those fitted at
the factory are used (this includes winter
tyres), the electron ic speedometer may
possibly need to be reprogrammed, to
ensure that the speed displayed is correct. Vehicles with tyre pressure monitoring
system

When using winter tyres, or when switching
to different tyre sizes, sensors for the tyre
pressure monitoring syst em can be fitted at
a later date by a workshop, upon request.
Otherwise, the system would not indicate
tyre pressure deviations.
Tyre pressure monitoring system -
see page 144.
Fitting new tyres
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 opposing 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
properties of the tyre.
Observe legal requirements 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 Opel for the respective vehicle and
comply with all of the relevant wheel and
tyre combination requ irements must be
used.
z If the wheel trims and tyres used are not
Opel-approved, the tyres must not have
a beaded edge.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.
9 Warning
Use of unsuitable tyres or wheel trims
could lead to sudden pressure loss and
thereby accidents.

Tyres
Restrictions
Not all tyres available on the market
currently meet the structural requirements.
We recommend that you consult an Opel
Partner concerning su itable tyre makes.
These tyres have undergone special tests
to establish their reliability, safety and
specific suitability for Opel vehicles.
Despite continuous market monitoring, we
are unable to assess these attributes for
other tyres, even if they have been granted
approval by the relevant authorities or in
some other form.
Further information - see page 149.
Winter tyres 3
Tyres of size 235/55 R 18 are not to be used
as winter tyres. Tyres of size 215/70 R 16,
235/60 R 17 and 235/65 R 17 may be used
as winter tyres.
Use of the spare wheel may alter vehicle
handling. Obtain a replacement for the
faulty tyre as soon as possible, and have
the wheel balanced and fitted to the
vehicle.
Further information - see page 152.
Tyre chains
Restrictions
We recommend the use of Opel-tested
fine-mesh tyre chains that add no more
than 15 mm to the tyre tread and the
inboard sides (including chain lock).
Tyre chains are permitted only on tyres of
size 215/70 R 16. We recommend you
consult your Opel Partner.
