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.
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.
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
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.

& WARNING Risk of accident caused by
non-approved tyre types
If you use tyre types that have not been
adapted to changes made to the factory
speed limit, this can have the following con‐
sequences:
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
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.
