Wheels and tyres

Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of
a workshop in the event of damage or
unusual wear.
Tyres
Tyres of size 225/45 R 17 are only
permitted if the vehicle is equipped
with electronic stability program.
Astra VXR: Permitted as winter tyres without tyre chains.
1)
Astra VXR "Nürburgring Edition"
with tyres 225/40 ZR 18
This model is factory-fitted with high-
performance sports tyres, size
225/40 ZR 18. These tyres are
approved for use on public roads but
have typical racing characteristics
and a correspondingly shallow tread.
The tyres provide sportily oriented
and experienced drivers with better
performance at faster speeds on dry
road surfaces but can cause the
vehicle to break away without
warning if this limit is exceeded. Avoid
adopting a risky driving style because
of this improved performance. In wet
conditions adapt your driving style
and speed to the shallow tread.

Winter tyres

Winter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.
Tyres of size 215/45 R 17,
225/45 R 17, 225/40 R 18
235/35 R 19 must not be used as
winter tyres.
Saloon, Hatchback, Estate, Van:
tyres of size 215/45 R 17 are only
approved as winter tyres if the vehicle
was equipped with 18-inch wheels in
the factory.
Winter tyres may only be used on the
Astra VXR on special alloy wheels
approved by Vauxhall.
Run-flat winter tyres may only be
used on factory approved alloy
wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.

Run-flat tyres

Run-flat tyres have reinforced, self-
supporting sidewalls, which ensure
that the tyres always have a certain
amount of driveability, even when
there is no pressure.
Run-flat tyres are only permitted on
vehicles with electronic stability
program and tyre pressure monitoring
and

system or deflation detection system.
