WARNING
ARNING Risk of accident with high per-
fo rm ance tyres
The special tyre tread in combination with the
optimised tyre compound means that therisk
of skidding and hydroplaning on wetro ads is
increased.
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 driv-
ing style accordingl y. #
Use i M+S tyres at outside temp era-
tures of less than 10 °C. #
Only use the tyres forth eir intended pur-
pose. Obser

di.er:
R front wheels wear more on the tyre shoulder
R rear wheels wear more in the centre of the
tyre
Do not drive with tyres that ha vetoo little tread
dep th. This signi/cantly reduces traction on wet
ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5,000 to10,000 km, depending on thewe ar.
