The special tyre tread in combination with
th e optimised tyre compound, means that
th erisk of skidding or 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 M+S tyres at outside temp eratures
of less than 50 °F. 394

Obser
vethefo llowing when selecting, fitting and
re placing tyres:
R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle.
Fu rthermore, 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 Only fit tyres of the cor rect size onto the
wheels.
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
Vehicles with a tyre pressure monitoring
sy stem: Allfitted wheels mu stbe equipped
with functioning sensors forth e tyre pres‐
sure monitoring sy stem.
R Attemp eratures below 7 °C, use winter tyres
or all-season tyres mar ked M+S for all
wheels.
Wi nter tyres bearing thei snowflake
symbol in addition tothe M+S marking pro‐
vide 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 is is below theve hicle's maximum speed,
th is must be indicated in an appropriate label
in the driver's field of vision.
R Run in new tyres at moderate speeds forthe
fi rs t10 0 km.
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
with MOExtended tyres are not equipped
with a TIREFIT kit at thefa ctor y.Equip the
