the risk of skidding or hydroplaning on wet
roads is increased.
In addition, the tyre grip is greatly reduced at
a low outside temperature and tyre running
temperature.
®
Switch on the ESP and adapt your
#
driving style accordingly.
Use M+S tyres at outside temperatures
#
of less than 50 °F.
Observe the following when selecting, fitting and
replacing tyres:
Country-specific requirements for tyre
R
approval that define a specific tyre type for
your vehicle.
Furthermore, the use of certain tyre types in
certain regions and areas of operation can
be highly beneficial.
Only use tyres and wheels of the same type
R
(summer tyres, winter tyres, MOExtended
tyres) and the same make.
Only fit wheels of the same size on one axle
R
(left and right).
It is only permissible to fit a different wheel
size in the event of a flat tyre in order to
drive to the specialist workshop.
Only fit tyres of the correct size onto the
R
wheels.
Do not make any modifications to the brake
R
system, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may invalidate the vehicle's
general operating permit.
Vehicles with a tyre pressure monitoring
R
system: all fitted wheels must be equipped
with functioning sensors for the tyre pres‐
sure monitoring system.
At temperatures below 7 °C, use winter tyres
R
or all-season tyres marked M+S for all
wheels.
Winter tyres bearing the i snowflake
symbol in addition to the M+S marking pro‐
vide the best possible grip in wintry road
conditions.
For M+S tyres, only use tyres with the same
R
tread.
Wheels and tyres 419
Observe the maximum permissible speed for
R
the M+S tyres fitted.
If this is below the vehicle's maximum speed,
this must be indicated in an appropriate label
in the driver's field of vision.
Run in new tyres at moderate speeds for the
R
first 100 km.
Replace the tyres after six years at the latest,
R
regardless of wear.
When replacing with tyres that do not
R
feature run-flat characteristics: vehicles
with MOExtended tyres are not equipped
with a TIREFIT kit at the factory. Equip the
vehicle with a TIREFIT kit after replacing with
tyres that do not feature run-flat characteris‐
tics, e.g. winter tyres.
For more information on wheels and tyres, con‐
tact a qualified specialist workshop.
