230 Driving and operation
General information
z The danger of aquaplaning is greater if
the tyres are worn.
z Tyres age, even if they are used only very
little or not at all. A spare wheel which
has not been used for six years should be
used only in emergencies; drive slowly
when using such tyres.
z Never fit used tyres the previous history
and use of which you do not know.
z So as not to impair brake cooling, use
only wheel trims approved for use on
your vehicle.
Tyre designations
Meanings:
e.g. 195/65 R 15 91 H
Speed code letters:
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.
195 = Tyre width in mm
65 = Cross-section ratio
(tyre depth to width) in %
R =Belt type: Radial
RF = Type: RunFlat
15 = Wheel diameter in inch
91 =Load index
e.g. 91 corresponds to 618 kg
H = Speed code letter:
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)
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.
