256Operation
Wheels and tires

MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires.
MOExtended tires may only be use dinconjunc-
tion 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 (
Ypag e242).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommendedt hat you additionally
equip you rvehicl ewithaTIREFIT kit if you mount
tires that do not feature run-fla tproperties, e.g.
winter tires. ATIREFIT kit can be obtained from
aq ualified specialist workshop.
Winter operation
General notes
Have you rvehicl ewinter-proofed at aqualified
specialist worksho patthe onset of winter.
Observe the notes in the "Changing awheel"
section (
Ypag e274).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on you rvehicle
to M+S tires .Using summe rtires at very cold
temperatures coul dcaus ecracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
GWARNING
Damaged tires can caus etire inflation pres-
sure loss. As aresult, you coul dlose control of
you rvehicle. There is arisk of accident.
Check the tires regularl yfor signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both type softire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibl egrip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e261).
XVehicles for Canada: restart the tire pres-
sure loss warning system (Ypag e262).
XRestart the tire pressure monitor
(Ypag e262).

Snowc hains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is arisk of an accident.

Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The whee lbrakes or suspension components
may als obedamaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with atire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be use dnear
the valve .This coul ddamage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Always pay attention to the instructions and
safety notes when changing awheel
(
Ypag e275).
The wea rpatterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclearw earp attern
has formed on the tires. Front tires typically
wea rmore on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the interval sinthe tire manufacturer's
warranty book in you rvehicl edocuments. If no
warranty book is available,t he tires should be
rotated every 3,000 to 6,000 mile s(5,000 to
10,000 km) .Depending on tire wear, this may
be required earlier. Do not change the direction
of whee lrotation.
Clean the contact surfaces of the whee land the
brake disc thoroughly every time awhee lisr ota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system or
the tire pressure monitor.
Directio nofrotation
Tires with aspecified direction of rotation have
additiona lbenefits, e.g. if there is arisk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.

Wheels and tires

These tires have been specially adapted for
use with the control systems, such as ABS or
ESP
®,and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz.C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with aload, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components .This
could result in damage to the tires or the vehi- cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Information on tires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
!Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz,s ince previ-
ous damage cannot alwaysbed etected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found:
Ron the Tire and Loading Information placard

Observe the notes on recommended tire pres-
sures under various operating conditions

Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet. Notes on the vehicle equipment

Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
