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.

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 205/65 R 16, 215/60 R 16 and
225/50 R 17.
The use of tyre chains is not permitted
on the temporary spare wheel.

Tyre repair kit

Minor damage to the tyre tread or
sidewall can be repaired with the tyre
repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's side wall near the rim
cannot be repaired with the tyre repair
