229 Driving and operation
Run-flat tyres (RFT) 3
Run-fla t tyres have reinforced, self-
sup porting sidewalls, w hich ensure that the
tyres a lways have a certain amount of
driveability, ev en when there is no p ressure.
Run-fla t tyres are only permitted on
vehic les with ESP®
Plus
and tyre pressure
monitoring system or defla tion detection
system.
Dep ending on tyre manufacturer, run-fla t
tyres c an be identified from a marking on
the tyre wa ll. E.g. ROF = Run-on-Flat for
Goodyear or S SR = Self Supporting R un-flat
Tyre for Continental.
Run-fla t tyres ma y only be used in
combination with Vauxhall-app rov ed alloy
wheels; this a lso app lies to winter tyres.
Driv ing with a dam aged tyre
A loss in tyre pressure is ind icated by the
tyre p ressure monitoring system 3 or the
deflation detection system 3 .
If a tyre has no pressure, continued driving
is p ossible
z at a sp eed of max. 50 mph (80 k m/h),
z up to a distance of 50 miles (80 k m).
Do not use a tyre repa ir kit.

Winter tyres 3
For notes on fitting new tyres – see
pag e 224.
Limitations - see pa ges 229, 337.
Winter tyres improve safety at
temperatures b elow 7 °C and should
therefore be fitted on all the wheels.
The design of summ er tyres means they
have limited qualities for winter driving.
If the maxim um perm issible speed for the
winter tyres is less than that of the v ehicle,
a notice indicating the m aximum
permissible sp eed for the tyres must b e
affixed within the driver’s field of v ision

.
If you use the spare wheel when it is fitted
with a summer tyre, the vehicle’s
driveability ma y be affected , especially on
slippery road surfaces. Obtain a
replacem ent for the faulty tyre as soon as
possible, and ha ve the wheel balanced
and fitted to the v ehicle.

Warning
Even the tyre pressure of run-flat tyres
must be checked regularly.
Check tyre pressures a t least ev ery
14 days and prior to any long journey;
the tyres should be checked when cold.

Warning
When driving w ith a flat tyre, do not
exceed a sp eed of 50 m ph (80 km /h) or
a d istance of 50 m iles (80 km ).
The vehicle will be more difficult to steer
and handle and the brak ing d istance will
be longer.
Adapt driving style and speed to the
conditions at hand.
