Page: 342 / 462

Observe the following when selecting, installing
and replacing tires:
R
Furthermore, the use of certain tire types in
certain regions and areas of operation can be
highly beneficial.
R
Only use tires and wheels of the same type
(summer tires, winter tires, MOExtended tires)
and the same make.
R
Only install wheels of the same size (left and
right) on each axle.
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.
R
Vehicles with a tire pressure monitoring sys-
tem: all installed wheels must be equipped
with functioning sensors for the tire pressure
monitoring system.
R
At temperatures below 45°F (7°C) use winter
tires or all-season tires marked
i
M+S for
all wheels.
Winter tires provide the best possible grip in
wintry road conditions.
R
For M+S tires, only use tires with the same
tread.
R
Observe the maximum permissible speed for
the M+S tire which is installed.
If the tire's maximum speed is below that of
the vehicle, this must be indicated by an
appropriate label in the driver's field of vision.
R
Break in new tires at moderate speeds for the
first 60 miles (100 km).
R
Replace the tires after six years at the latest,
regardless of wear.
R
When replacing with tires that do not feature
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.
