Winter Tyres; Run-Flat Tyres - Opel Automobile Owner's Manual

190 Vehicle care
Astra OPC "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.
Astra OPC: Permitted as winter tyres without tyre chains.

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
1) ,
vehicles with electronic stability
program and tyre pressure monitoring
system or deflation detection system.
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
Use of run-flat tyres is only permitted
in combination with factory approved
alloy wheels.
