Mercedes-Benz 2013 GL Class - Manual (Page 398)

Selecting, mounting and replacing
tires
R
Only mount tires and wheels of the same
type and make.
R
Only mount tires of the correct size onto
the wheels.
R
Break in new tires at moderate speeds for
the first 60 miles (100 km). They only reach
their full performance after this distance.
R
Do not drive with tires which have too little
tread depth. as this significantly reduces
the traction on wet roads (hydroplaning).
R
Replace the tires after six years at the
latest, regardless of wear.
Observe the notes on the emergency spare
wheel (
Y page 427).
MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires.
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tires with
a flat tire (
Y page 378).
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from a
qualified specialist workshop.
Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (
Y page 416).
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your
vehicle to M+S tires. Using summer tires at
very cold temperatures could cause cracks to
form, thereby damaging the tires
permanently. Mercedes-Benz cannot accept
responsibility for this type of damage.
M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There
is a risk of an accident.
M+S tires with a tread depth of less than ã
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡ (+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking
provide the best possible grip in wintry road
conditions.
Only these tires will allow driving safety
systems such as ABS and ESP
® to function
optimally in winter. These tires have been
developed specifically for driving in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.
