Wheels and tires

Observe the legally required minimum tire tread
depth ( Y
page 288). Winter tires can reduce the
braking distance on snow-covered surfaces in
comparison with summer tires. The braking dis-
tance is still much further than on surfaces that
are not icy or covered with snow. Take appro-
priate care when driving.
Further information on winter tires (M+S tires)
( Y
page 289).
Temperature
G WARNING
The temperature grade for this tire is estab-
lished for at ire that is properly inflated and
not overloaded .E xcessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause excessive heat
build-up and possible tire failure.
The temperature grades are A( the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on as pecified indoor laboratory test wheel. Sus-
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade Cc orresponds to al evel of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades Ba nd Ar epresent
higher levels of performance on the laboratory
test wheel than the minimum required by law. Tire labeling

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.
Storing wheels Stor ew heels that are not being used in ac ool,
dry and preferably dark place. Protec tt he tires
from oil, grease, gasoline and diesel. Mounting aw heel
