400 Wheels and tires
of skidding or hydroplaning on wet roads is
increased.
In addition, the tire grip is greatly reduced at
a low outside temperature and tire running
temperature.
®
Switch on the ESP and adapt your
#
driving style accordingly.
Use M+S tire at outside temperatures
#
of less than 10 °C (50 °F).
Observe the following when selecting, installing
and replacing tires:
Only use tires and wheels of the same type
R
(summer tires, winter tires, MOExtended
tires) and the same make.
Only install wheels of the same size on one
R
axle (left and right).
It is only permissible to install a different
wheel size in the event of a flat tire in order
to drive to the specialist workshop.
Only install tires of the correct size onto the
R
wheels.
Vehicles with a tire pressure monitoring
R
system: All installed wheels must be equip‐
ped with functioning sensors for the tire
pressure monitoring system.
At temperatures below 45 °F (7 °C), use win‐
R
ter tires or all-season tires marked M+S for
all wheels.
Winter tires bearing the i snowflake sym‐
bol in addition to the M+S marking provide
the best possible grip in wintry road condi‐
tions.
For M+S tires, only use tires with the same
R
tread.
Observe the maximum permissible speed for
R
the M+S tires installed.
If this is below the vehicle's maximum speed,
this must be indicated by an appropriate
label in the driver's field of vision.
Break in new tires at moderate speeds for
R
the first 60 miles (100 km).
Replace the tires after six years at the latest,
R
regardless of wear.
When replacing with tires that do not fea‐
R
ture run-flat characteristics: vehicles with
MOExtended tires are not equipped with a
TIREFIT kit at the factory. Equip the vehicle
with a TIREFIT kit after replacing with tires
that do not feature run-flat characteristics,
e.g. winter tires.
