On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Various types of steel wheel can be fitted on
your vehicle. Some steel wheels have a red
mark in the hub cap area. The hub cap has to be
removed to see the red mark, see "Raising the
vehicle" in the "Wheel change" section
(
Y page 208). When changing the wheels,
always fit wheels of the same type on all axles.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Always pay attention to the instructions and
safety notes when changing a wheel
(
Y page 206).
The wear patterns on the front and rear tyres
differ, depending on the operating condi-
tions. Front tyres typically wear more on the
shoulders and the rear tyres in the centre.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and
reactivate the tyre pressure monitor if nec-
essary.
Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a
risk of aquaplaning. These advantages can
only be gained if the tyres are fitted corre-
sponding to the direction of rotation.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
Storing wheels
Store wheels in a cool, dry and preferably
dark place if they are not being used. Protect
the tyres against oil, grease, petrol and die-
sel.
