Mercedes-Benz AMG GT Operator's Manual page 363

Observe the following when selecting, installing
and replacing tires:
Furthermore, the use of certain tire types in
R
certain regions and areas of operation can be
highly beneficial.
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.
Vehicles with a tire pressure monitoring sys-
R
tem: all installed wheels must be equipped
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 i M+S
for all wheels.
Winter tires provide the best possible grip in
wintry road conditions.
For M+S tire, only use tires with the same
R
tread.
Observe the maximum permissible speed for
R
the M+S tire 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.
Break in new tires at moderate speeds for the
R
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 feature
R
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.
