Tyre designations
Meanings:
e.g. 195/65 R 15 91 H
195 =Tyre width in mm
65 = cross-section ratio
(tyre height to tyre width) in %
R = belt type: R adial
RF = type: RunFlat
15 = rim diameter in inch
91 =load index
z. B.: 91 corresponds to 618 kg
H = speed code
Speed code letters:
Q Up to 100 mph (160 km/h)
S Up to 112 mph (180 km/h)
T Up to 118 mph (190 km/h)
H Up to 130 mph (210 km/h)
V Up to 150 mph (240 km/h)
W Up to 168 mph (270 km/h)
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 = RunonFlat for
Goodyear or SSR = Self Supporting Runflat
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 – page 221,
tyre pressure monitoring system 3
– page 222.
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.
