Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at aq ualified spe-
cialist workshop.
Observe the instructions and safety notes in the
"Changing aw heel" section ( Y
page 307).
The wear pattern sont he front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before ac lear wear pattern
has formed on the tires. Fron tt ires typically
wear more on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotat et he wheels accord-
ing 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
10,00 0k m) .D ependin gont ire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time aw heel is rota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system
(Canada only) or the tire pressure monitor (USA
only).
Direction of rotation Tires with as pecified direction of rotation have
additional benefits ,e .g. if there is ar isk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
An arrow on the sidewall of the tire indicates its
correc td irection of rotation.
