390 Wheels and 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 sys-
R
tem: all fitted wheels must be equipped with
functioning sensors for the tyre pressure mon-
itoring system.
At temperatures below 7°C use winter tyres or
R
all-season tyres marked M+S for all wheels.
Winter tyres bearing the i snowflake sym-
bol in addition to the M+S marking provide the
best possible grip in wintry road conditions.
For M+S tyres, only use tyres with the same
R
tread.
Observe the maximum permissible speed for
R
the M+S tyres fitted.
If the tyre's maximum speed is below that of
the vehicle, this must be indicated by 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 feature
R
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 characteristics,
e.g. winter tyres.

You can permanently limit the speed for driv-
ing with winter tyres ( page 225).

& WARNING Risk of accident caused by
non-approved tyre types
If you use tyre types that have not been adap-
ted to changes made to the factory speed
limit, this can have the following consequen-
ces:
The tyres are not suitable for high speeds
R
and the corresponding driving dynamics.
The tyres wear unevenly and affect the
R
roadworthiness of the vehicle.
®
ABS, ESP and cruise control operation
R
are restricted.
This can jeopardise road safety.
Only use tyre types that have been
#
approved for the maximum permissible
speed set and the vehicle.
Notes on interchanging wheels
& WARNING Risk of injury through different
wheel sizes
Interchanging the front and rear wheels can
severely impair the driving characteristics.
The disk brakes or wheel suspension compo-
nents may also be damaged.
