Rotating the wheels
GWARNING
Interchangingthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There isarisk of
accident.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
!On vehicles equipped withatire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed ataqualified
specialist workshop.
Always observe the instructions and safety
notes in the "Mountingawheel" section
(Ypage 358).
The wear patternsonthe front and rear tires
differ, depending on the operating conditions.
Rotate the wheels beforeaclear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
available, the tires should then be replaced
every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if the tire wear requires
this. Do not change the direction of wheel
rotation.
Cleanthe contact surfaces of the wheel and
the brake disc thoroughly every timeawheel
is interchanged. Check the tire pressure and,
if necessary, restart the tire pressure loss
warning system or the tire pressure monitor.
Direction of rotation
Tires withaspecified direction of rotation
have additional benefits, e.g. if there isarisk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
maintained.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
Storing wheels
Storewheels that are not being used inacool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.
