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 185/65 R 15,
195/60 R 15, 195/65 R 15 and
205/55 R 16 can be used as winter
tyres.
Tyres of size 205/50 R17 must only
be used as winter tyres.
Tyres of size 215/45 R 17,
225/45 R 17, 225/40 R 18
1)
and
235/35 R 19 must not be used as
winter tyres.
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
system or deflation detection system.
Caution
Check tyre pressures regularly
even if run-flat tyres are fitted.
Depending on tyre manufacturer, run-
flat tyres can be identified from
a marking on the tyre wall. E.g.
ROF = RunonFlat for Goodyear or
SSR = Self Supporting Runflat Tyre
for Continental.
Use of run-flat tyres is only permitted
in combination with factory approved
alloy wheels.
