Changing tyre and wheel size

If tyres of a different size than those
fitted at the factory are used, it may be
necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.
9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.

Wheel covers

Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Wheel caps
Tyres of size 245/35 R20 have
a specific wheel cap. To remove the
cap from the dismantled wheel first
disengage the arms one by one. Then
press the cap in the middle area from
behind and remove it.
To assemble first adjust the wheel
cap in order that the positioning leg
fits into the recess.

Tyre chains

Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add
no more than 10 mm to the tyre tread
and the inboard sides (including chain
lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are not permitted on tyres
of size 225/55 R 17, 245/45 R 18,
245/40 R 19 and 245/35 R 20.
