Run-flat tyres (RFT) 3
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 ESP®
Plus
and tyre pressure
monitoring system or deflation detection
system.
Depending on tyre manufacturer, run-flat
tyres can be identified from a marking on
the tyre wall. E.g. ROF = Run-on-Flat for
Goodyear or SSR = Self Supporting Run-flat
Tyre for Continental.
Run-flat tyres may only be used in
combination with Vauxhall-approved alloy
wheels; this also applies to winter tyres.
Driving with a damaged tyre
A loss in tyre pressure is indicated by the
tyre pressure monitoring system 3 or the
deflation detection system 3.
If a tyre has no pressure, continued driving
is possible
z at a speed of max. 50 mph (80 km/h),
z up to a distance of 50 miles (80 km).
Do not use a tyre repair kit.
Deflation detection system 3 – see
page 217, tyre pressure monitoring
system 3 – see page 218.
Winter tyres 3
For notes on fitting new tyres – see
page224.
Limitations - see pages 229, 337.
Winter tyres improve safety at
temperatures below 7 °C and should
therefore be fitted on all the wheels.
The design of summer tyres means they
have limited qualities for winter driving.
If the maximum permissible speed for the
winter tyres is less than that of the vehicle,
a notice indicating the maximum
permissible speed for the tyres must b e
affixed within the driver’s field of vision

.
If you use the spare wheel when it is fitted
with a summer tyre, the vehicle’s
driveability may be affected, especially on
slippery road surfaces. Obtain a
replacement for the faulty tyre as soon as
possible, and have the wheel balanced
and fitted to the vehicle.
9 Warning
Even the tyre pressure of run-flat tyres
must be checked regularly.
Check tyre pressures at least every
14 days and prior to any long journey;
the tyres should be checked when cold.
9 Warning
When driving with a flat tyre, do not
exceed a speed of 50 mph (80 km/h) or
a distance of 50 miles (80 km).
The vehicle will be more difficult to steer
and handle and the braking distance will
be longer.
Adapt driving style and speed to the
conditions at hand.
