WARNING Risk of accident with high
per form ance tyres
The special tyre tread in combination with
th e optimised tyre compound means that the
ri sk of skidding and hydroplaning on wet
ro ads is inc reased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use 004D M+S tyres at outside temp er‐
atures of less than 10 °C. #
Only use the tyres forth eir intended
purpose. Obser

re placing tyres:

Furthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
tyres) and the same make.
R Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
size in theeve nt of a flat tyre in order to
drive tothe specialist workshop.
R Do not make any modifications tothe brake
sy stem, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may in validate theve hicle's
ge neral operating pe rmit.

R Attemp eratures below 7 °C use winter tyres
or all-season tyres mar ked004D M+Sfor all
wheels. Wi
nter tyres pr ovide the best possible grip in
wintry road conditions.
R For M+S tyres, only use tyres with the same
tread.
R Obser vethe maximum permissible speed for
th e M+S tyres fitted.
If th e tyre's maximum speed is below that of
th eve hicle, this must be indicated byan
appropriate label in the driver's field of

R Run in new tyres at moderate speeds forthe

R Replace the tyres af ter six years at the latest,
re ga rdless of wear.
R When replacing with tyres that do not
fe ature run-flat characteristics: vehicles

tyres that do not feature run-flat characteris‐
tics, e.g. winter tyres. %
You can permanently limit the maximum

#
Only inter change the front and rear
wheels if the wheels and tyres ha vethe
same dimensions. Inter
changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions can
re nder thege neral operating pe rmit in valid.
The wear pat tern s on the front and rear wheels
dif fer:
R front wheels wear more on the tyre shoulder
R rear wheels wear more in the cent reofthe
tyre
Do not drive wi thtyres that ha vetoo little tread
dep th. This significantly reduces traction on wet
ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels.
