WARNING Risk of accident wi thhigh
per form ance tires
The special tire tread in combination with the
optimized tire compound means that therisk
of skidding or hydroplaning on wetro ads is
inc reased.
In addition, the tire grip is greatly reduced at
a low outside temp erature and tire running
te mp erature.
#Switch on the ESP®and adapt your

ROnly mount wheels of the same size on one
axle (left and right).
It is only permissible todeviate from this rule
in theeve nt of a flat tire in order todrive to
th e specialist workshop.
ROnly mount tires of the cor rect size onto the
wheels.
RVe hicles with a tire pressure monitoring
sy stem: All mounte d wheels must be equip‐
ped with functioning sensors forth e tire
pressure monitoring sy stem.
RAt temp eratures below 45 °F (7 °C), use win‐
te r tires or all-season tires mar ked M+S for
all wheels.

RObser vethe maximum permissible speed for
th e M+S tire mounted.
If th is is below theve hicle's maximum speed,
th is must be indicated in an appropriate label
in the driver's field of vision.
RBreak in new tires at moderate speeds for

WARNING Risk of injury thro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels if the
wheels or tires ha vediffere nt dimensions
may se verely impair the driving characteris‐
tics.
The wheel brakes or wheel suspension com‐
ponents may also be damaged.
#Ro tate front and rear wheels only ifth e
wheels and tires are of the same dimen‐
sions.

Thewear patte rns on the front and rear wheels
dif fer:
RFr ont wheels wear more on the shoulder of
th e tire
RRe ar wheels wear more in the center of the
tire
On vehicles that ha vethe same size front and
re ar wheels, inter change the wheels according
to the inter vals in the tire manufacturer's war‐
ra nty book in your vehicle documents. If this is
not available, inter change the tires every
3,000 to6,000 miles (5,000to10,000 km),
depending on thewe ar. Ensure that the direction
of rotation is maintained.
It is impe rative toobser vethe instructions and
saf etyno tes on "Wheel change" when doing so.
Note s onstoring wheels
RAf terre moving wheels, store them in a cool,
dry and preferably dark place.
RPr otect the tires from conta ct withoil, grease
or fuel.
