in the center.
If your vehicle's tire configuration allows, you
can rotatet he wheels according to the intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles
(5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of wheel rotation.
Clean the contac tsurface softhe wheel and
the brake disc thoroughly every time awheel
is rotated. Check the tire pressure and, if
necessary, restart the tire pressure loss
warning system or the tire pressure monitor. Direction of rotation
Tires with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
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
Storew heels that are not being used in acool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel. Cleaningt
