brake system and in the wheel suspension
may be damaged.Always replace wheels and tires with
ones that fulNll the speciNcations of the
original part.
For wheels, pay attention to the following:
= Designation
= Type
For tires, pay attention to the following: = Designation
= Manufacturer
= Type
&WARNING Risk of injury through exceed-
ing the speciNed tire load-bearing capa-
city or the permissible speed rating
Exceeding the speciNed tire load rating or the
permissible speed rating may lead to tire dam-
age and to the tires bursting.
Therefore, only use tire types and sizes
approved for your vehicle model.Observe the tire load rating and speed
rating required for your vehicle.*NOTE Vehicle and tire damage caused by
non-approved tire types and sizes
For safety reasons, only use tires, wheels and
accessories which have been specially
approved by Mercedes-Benz for your vehicle.
These tires are specially adapted to the active safety systems, such as ABS, ESP n
and
4MATIC, and marked as follows:
= MO = Mercedes-Benz Original
= MOE = Mercedes-Benz Original Extended
(run-Oat tires only for certain wheels)
= MO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Otherwise, certain properties, such as han-
dling characteristics, vehicle noise emissions,
consumption, etc. could be adversely aMec-
ted. Furthermore, other tire sizes could result
in the tires rubbing against the body and axle
components when loaded. This could result in
damage to the tire or the vehicle.
Only use tires, wheels and accessories that have been checked and recommended by
Mercedes-Benz.*NOTE Risk to driving safety from retrea-
ded tires
Retreaded tires are neither tested nor recom- mended by Mercedes-Benz, since previous
damage cannot always be detected on retrea-
ded tires.
For this reason driving safety cannot be guar-
anteed.
Do not use used tires if you have no information about their previous usage.*NOTE Possible wheel and tire damage
when driving over obstacles
Large wheels have a smaller section width. As
the section width decreases, the risk of
Wheels and tires351

wheels and tires being damaged when driving
over obstacles increases.Avoid obstacles or drive especially care-
fully.Reduce your speed when driving over
curbs, speed bumps, manhole covers and potholes.Avoid particularly high curbs.*NOTE Possible wheel and tire damage
when parking on curbs or in potholes
Parking on curbs or in potholes can damage
the wheels and tires.
Only park on as level a surface as possi-
ble.Avoid curbs and potholes when parking.*NOTE Damage to electronic component
parts due to the use of tire-installing tools
Vehicles with tire pressure monitoring sys-
tem: There are electronic component parts in
the wheel.
If tire-installing tools are positioned in the area
of the valve, the electronic components could be damaged.Tire-installing tools should not be applied
in the area of the valve.Always have tires change at a qualiNed
specialist workshop.*NOTE Damage to summer tires at low
ambient temperatures
At low ambient temperatures, tears could form
when driving with summer tires, causing per-
manent damage to the tires.
At temperatures below 45 °F (7 °C) use M M\fS tires.
Accessory parts which are not approved for your
vehicle by Mercedes-Benz, or which are not used
correctly, can impair the operating safety.
Before purchasing and using non-approved acces-
sories, visit a qualiNed specialist workshop and
inquire about:
= Suitability
=Legal stipulations
= Factory recommendations&WARNING Risk of accident with high per-
formance tires
The special tire tread in combination with the
optimized tire compound means that the risk of skidding and hydroplaning on wet roads is
increased.
In addition, the tire grip is greatly reduced at a
low outside temperature and tire running tem-
perature.
Switch on the ESP n
and adapt your driv-
ing style accordingly.Use M M\fS tires at outside tempera-
tures of less than 50 °F (10 °C).Only use the tires for their intended pur-
pose.352Wheels and tires

Observe the following when selecting, installing
and replacing tires:
= Furthermore, the use of certain tire types in
certain regions and areas of operation can be
highly beneNcial.
= Only use tires and wheels of the same type
(summer tires, winter tires, MOExtended tires)
and the same make.
= Only install wheels of the same size (les and
right) on each axle.
It is only permissible to install a diMerent
wheel size in the event of a Oat tire in order to
drive to the specialist workshop.
= Vehicles with a tire pressure monitoring sys-
tem: all installed wheels must be equipped
with functioning sensors for the tire pressure
monitoring system.
= At temperatures below 45°F (7°C) use winter
tires or all-season tires marked M M\fS for
all wheels.
Winter tires provide the best possible grip in
wintry road conditions.= For M\fS tires, only use tires with the same
tread.
= Observe the maximum permissible speed for
the M\fS tire which is installed.
If the tire\bs maximum speed is below that of
the vehicle, this must be indicated by an
appropriate label in the driver\bs Neld of vision.
= Break in new tires at moderate speeds for the
Nrst 60 miles (100 km).
= Replace the tires aser six years at the latest,
regardless of wear.
= When replacing with tires that do not feature
run-Oat characteristics: vehicles with
MOExtended tires are not equipped with a
TIREFIT kit at the factory. Equip the vehicle with a TIREFIT kit aser replacing with tires that
do not feature run-Oat characteristics, e.g.
winter tires.
For more information on wheels and tires, contact
a qualiNed specialist workshop.
Be sure to also observe the following further rela-
ted subjects:
= Notes on tire pressure (  page 333)=
Tire and loading information placard
(  page 338)
= Tire size designation, load-bearing capacity,
speed rating and load index (  page 346)
= Tire pressure table (  page 335)
= Notes on the emergency spare wheel
(  page 360)
Notes on rotating wheels
&WARNING Risk of injury through diMerent
wheel sizes
Rotating the front and rear wheels can
severely impair the driving characteristics.
The wheel brakes or suspension components
may also be damaged.
Rotate front and rear wheels only if the
wheels and tires are of the same dimen-
sions.
Observe the instructions and safety notes on
"Changing a wheel" (  page 350)
Wheels and tires353

The wear patterns on the front and rear wheels
diMer:
= Front wheels wear more on the tire shoulder
= Rear wheels wear more in the center of the
tire
Do not drive with tires that have too little tread
depth. This signiNcantly reduces traction on wet
roads (hydroplaning).
On vehicles that have the same size front and rear
wheels, rotate the wheels according to the inter- vals in the tire manufacturer\bs warranty book in
your vehicle documents. If this is not available, rotate the tires every 3,000 to 6,000 miles(5,000 to 10,000 km), depending on the wear.Ensure that the direction of rotation is main-
tained.
Notes on storing wheels
When storing wheels, observe the following notes:
= Aser removing wheels, store them in a cool,
dry and preferably dark place.
= Protect the tires from contact with oil, grease
or fuel.
