Wheels and tyres

Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
We recommend not swapping the
front wheels with the rear wheels and
vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.

Winter tyres

Winter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.

Tyre designations

195 : tyre width, mm
55 : cross-section ratio (tyre height
to tyre width), %
R : belt type: Radial
RF : type: RunFlat
16 : wheel diameter, inches
91 : load index e.g. 91 is equivalent
to 615 kg
H : speed code letter

S : up to 112 mph
T : up to 118 mph

maximum speed of your vehicle.

the vehicle.
Performance 3 178.
Directional tyres
Directional tyres must be mounted so
that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.

Tyre pressure

Check the pressure of cold tyres at
least every 14 days and before any
long journey.
Do not forget the spare wheel.
This also applies to vehicles with tyre
pressure monitoring system.
Unscrew the valve cap.
