General: dependingonthemanufacturer's
standards ,the sizeimprinted in th etirew all
may no tcontai nany letters or may contain
on elette rthat precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to
European manufacturing standards.
If "P" precedes the size description: these are
passenger vehicle tires according to U.S.
manufacturing standards.
If "LT" precedes the size description: these
are light truck tires according to U.S.
manufacturing standards.
If "T" precedes the size description: these are
compact emergency spare wheels at high tire
pressure, to be used only temporarily in an
emergency.
Tire width: tire width001Ashows the nominal
tire width in millimeters.
Nominal aspect ratio: aspect ratio0010is the
size ratio between the tire height and the tire
width and is shown in percent.T he aspectratio is calculated by dividing the tire width by
the tire height.
Tire code:
tire code0023specifies the tire type.
"R" represents radial tires; "D" represents
diagonal tires; "B" represents diagonal radial
tires.
Optionally, tires with amaximum speed of
over 149mph (240km/h) may have "ZR"in
the size description, depending on the
manufacturer (e.g. 245/40 ZR 18).
Rim diameter: rim diameter0021is the
diameter of the bead seat, not the diameter
of the rim flange. The rim diameter is
specified in inches (in).
Load bearing index: load bearing index001E
is an umerical code which specifies the
maximum load-bearing capacity of atire.
Do not overload the tires by exceeding the
specified load limit. The maximum
permissible load can be found on the
vehicle's Tire and Loading Information
placard on the B-pillar on the driver's side
(Y page 323).
Example:
Al oad-bearing index of 91 indicates a
maximum load of 1,356lb (615kg) that can be
carried by the tires. For further information on
the maximum tire load in kilograms and
pounds, see (Y page 327).
For further information on the load-bearing
index, see Load index (Y page 332).
Speed rating: speed rating0024specifies the
approved maximum speed of the tire. G
WARNING
Exceeding the stated tire load-bearing
capacity and the approved maximum speed
could lead to tire damage or the tire bursting.
There is arisk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load rating and speed rating required for
your vehicle.
Regardless of the speed rating, always
observe the speed limits. Drive carefully and 330

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
nch)

Aspect ratio
Relationship between tire height and tire
widt hinp ercent. Tire pressure
This is pressur einside th etirea pplyin gan
outward force to eac hsquar einc hoft hetire's
surface. The tire pressur eisspecifie din
pounds per squar einc h( psi), in kilopascal
(kPa) or in bar. The tire pressur eshould only
be correcte dwhen th etires are cold. Tire pressure of cold tires
The tires are cold:
R if th evehicl ehas been parked without
direct sunligh tonthe tires for at least three
hours and
R if the vehicle has not been driven further
than 1mile (1.6 km) Tread
The part of the tire that comes into contact
with the road. Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim. Sidewall
The part of the tire between the tread and the
bead. Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
part and more than 2.3 kg (5 lbs). These optional extras, such as high-performance
brakes, level control,
aroof rack or ahigh-
performance battery, are not included in the
curb weight and the weight of the
accessories. TIN (Tire Identification Number)
This is aunique identifier which can be used
by atire manufacturer to identify tires, for
example for aproduct recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufacturing date. Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of atire. Traction
Traction is the result of friction between the
tires and the road surface. Treadwear indicators
Narrow bars (tread wear bars) that are
distributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 0003in
(1.6 mm) has been reached. Occupant distribution
The distribution of occupants in avehicle at
their designated seating positions. Total load limit
Nominal load and luggage load plus
68 kilograms (150 lb) multiplied by the
number of seats in the vehicle. Definition of termsf

The followin
gmust be observe dwhen
raisin gthe vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If used
incorrectly ,the jack coul dtip over with the
vehicle raised.
R the jack is designed only to raise and hold
the vehicle for ashort time while awheel
is being changed .Itisnot suited for
performing maintenance work under the
vehicle.
R avoid changing the wheel on uphilla nd
downhill slopes.
R before raising the vehicle, secure it from
rolling awaybya pplying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
R the jack must be placed on afirm, flat and
non-slip surface. On aloose surface, a
large, load-bearing underlay must be used.
On aslippery surface, anon-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as ajack underlay.O therwise, the
jack will not be able to achieve its load-
bearing capacity du etothe restricted
height.
R make sure tha tthe distance between the
underside of the tires and the ground does
not exceed 1.2 in (3 cm).
R never place your hands and feet under the
raised vehicle.
R never lie under the raised vehicle.
R never start the engine when the vehicle is
raised.
R never open or close adoor or the trunk lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised.
! The jack is designed exclusively for
jackingupt he vehicle at the jackingp oints.
Otherwise, your vehicle could be damaged. X
Using lug wrench 001A,loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely. The jackingp
oints are located just behind the
wheel housings of the front wheels and just
in front of the wheel housings of the rear
wheels (arrows).
X Take the ratchet wrench out of the tire-
changing tool kit and place it on the
hexagon nut of the jack so that the letters
AUF are visible. X
