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
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
for Continental.
Use of run-flat tyres is only permitted
in combination with factory approved
alloy wheels.
Do not use a tyre repair kit.
The ECO tyre pressure must not be
used.
Run-flat tyres must not be combined
with standard tyres.
If converting to standard tyres, note
that the vehicle is not equipped with
a spare wheel or tyre repair kit.
