The service specifications consist of load

R If the size description of you rtire includes
"ZR" and there are no service
specifications, ask the tir emanufacturer in
order to fin dout the maximum speed.
If as ervice specification is available, the
maximum speed is limited accordin gtothe
speed rating in the service specification.
Example: 245/4 0ZR1897Y.Int his
example, "97 Y" is the service specification.
The letter "Y" represents the speed rating
and the maximum speed of the tir eis
limited to 186 mph (300km/h).
R The size description for all tires with
maximum speeds of over 186mph
(300km/h )must include "ZR", andthe service specification must be given in
brackets. Example: 275/4
0ZR18(99 Y).
The speed rating "(Y)" indicates that the
maximum speed of the tir eisover 186mph

Not all tires with the M+S marking provide
the drivin gcharacteristics of winter tires.
Winter tires have, in additio ntothe M+S
identification, the 000Esnow flake symbol
on the tire sidewall. Tires with this marking
fulfill the requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC)
regarding the tire traction on snow. They
have been especially developed for driving
on snow.
An electronic speed limiter prevent syour
vehicle from exceeding aspeed of 130mph
(210km/h).
The speed rating of tires mounted at the
factor ymay be higher than the maximum
speed that the electronic speed limiter
permits.
Make sure that your tires have the required
speed rating, e.g. when buying new tires. The
required speed rating for your vehicle can be
found in the "Tires" section (Y page 340).
Further information about reading tire data
can be obtained from any qualified specialist
workshop.

GAWR (Gross AxleW
eight Rating)
The GAWR is the maximu mgross axle weight
rating. The actua lloa donana xle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicl eidentification plate on the B-pillar on
the driver's side. Speed rating
The spee drating is part of the tire
identification. It specifies the spee drange for
which the tire is approved. GVW (Gross Vehicle Weight)
The gross vehicl eweight includes the weight
of the vehicl eincluding fuel ,tools, the spare
wheel, accessories installed, occupants,
luggage and the drawbar noseweight, if
applicable.T he gross vehicle weight must not
exceed the gross vehicle weight rating GVWR
as specified on the vehicle identification plate
on the B-pillar on the driver's side. GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of afully loaded vehicle (the weight of
the vehicle including all accessories,
occupants, fuel, luggage and the drawbar
noseweight, if applicable). The gross vehicle
weight rating is specified on the vehicle
identification plate on the B-pillar on the
driver's side. Maximum loaded vehicle weight
The maximum weight is the sum of:
R the curb weight of the vehicle
R the weight of the accessories
R the load limit
R the weight of the factory installed optional
equipment Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa
corresponds to 1psi. Another unit for tire
pressure is bar. 100 kilopascal (kPa) is the
equivalent of 1bar. Load index
In addition to th eload-bearing index ,the load
index may also be imprinted on th esidewall
of th etire. This specifie sthe load-bearing
capacity more precisely. Curb weight
The weight of avehicle with standard
equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air-
conditioning system and optional equipment
if these are installed in the vehicle, but does
not include passengers or luggage. Maximum load rating
The maximum load rating in kilograms or
pounds is the maximum weight for which a
tire is approved. Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire. Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two. PSI (pounds per squarei

General notes
! For safety reasons, Mercedes-Benz
recommends that you only use tires and
wheels which have been approved by
Mercedes-Benz specifically for your
vehicle. These tires have been speciallya
dapted for
use with the control systems ,such as ABS
or ESP ®
,a nd are marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-BenzO riginal Extended
(tires featuring run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (only
certain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specificall yapproved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
vehicl enoise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, tire dimension variations coul dcause
the tires to come into contact with the
bodywork and axle components. This could
resul tind amage to th etires or th evehicle.
Mercedes-Ben zaccepts no liability for
damag eresulting from the us eoftires,
wheel soraccessorie sothe rthan those
tested and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
! Retreaded tires are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be
detected on retreaded tires. As aresult,
Mercedes-Ben zcannot guarante evehicle
safety if retreade dtires are mounted. Do
no tm ount used tires if you have no
information about their previous usage.
Overview of abbreviations used in the
following tire tables:
R BA: both axles
R FA: front axle
R RA: rear axle 340
Wheel and tirec
ombinationsWheels and tires

The recommended pressures for various
operating conditions can be found:
R
on the Tire and Loading Information placard
with the recommended tire pressures on
the B-pillar on the driver's side
R in the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions
(Y page 315).
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 –always
equip the vehicle with:
R tires of the same size on agiven axle (left/
right)
R the same type of tires at agiven time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to install a
differen ttype or mak einthe event of aflat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Y page 295).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory.
It is therefore recommended that you
additionall yequip your vehicle with aTIREFIT
kit if you mount tires that do not feature run-
flat properties, e.g. winter tires. ATIREFIT kit
may be obtained from aqualified specialist
workshop.
i The following pagesc ontain information
on approved wheelr im and tire sizes for
equipping yourv ehicle with winter tires.
Winter tires are not available at the factory
as standard equipment or optional extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size. The size of the approved winter tires
may differ from the standard tires. This is dependen
tonthe model and the
equipment installed at the factory.
The tires and wheel rims, as well as further
information ,can be obtained at aqualified
specialist workshop.
In the following table, the wheel/tire
combinations are assigned to the vehicle
models through variants, e.g. V1, V2 etc.: V1 B2

i Apart from some country-specific
variants, the vehicles are not equipped with
an emergency spare wheel. Emergency
spare wheels are specifi ctothe vehicle. For
more information on which emergency
spare wheels are approved for your vehicle,
consult aqualified specialist workshop.
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as
necessary (Y page 315). The value on the
