Tire size designation, load-bearing
capacity and speed rating
GWARNING
Exceeding the stated tire load-bearing
capacity and the approved maximum speed
could lead to tire damage or the tire burst- ing. There is a risk 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.

General: depending on the manufacturer's
standards, the size imprinted in the tire wall may not contain any letters or may contain one
letter that precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to Euro-
pean 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. man-
ufacturing standards.
If "T" precedes the size description: compact
emergency wheels with high tire pressure
that are only designed for temporary use in an
emergency.
Tire width: tire width0043shows the nominal
tire width in millimeters.
Height-width ratio: aspect ratio0044is the
size ratio between the tire height and tire
width and is shown in percent. The aspect
ratio is calculated by dividing the tire width
by the tire height.
Tire code: tire code0087specifies the tire
type. "R" represents radial tires; "D" repre-
sents diagonal tires; "B" represents diago-
nal radial tires.

Rubber Association of Canada (RAC)
regarding the tire traction on snow. They
have been especially developed for driving
on snow.
An electronic speed limiter prevents your
vehicle from exceeding a speed of 130 mph
(210 km/h).
The speed rating of tires mounted at the fac-
tory may 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 (
Ypage 200).
Further information about reading tire data
can be obtained from any qualified special-
ist workshop.
Load index
In addition to the load-bearing index, load
rating 0043may also be imprinted on the side-
wall of the tire. This is located after the let-
ters that identify the speed rating
(
Ypage 191).
RIf no specification is given: no text (as in
the example above), represents a standard
load (SL) tire
RXL or Extra Load: represents a reinforced
tire
RLight Load: represents a light load tire
RC, D, E: represents a load range that
depends on the maximum load that the tire
can carry at a certain pressure
iTire data is vehicle-specific and may
deviate from the data in the example.
Maximum load rating
Maximum tire load 0043is the maximum per-
missible weight for which the tire is
approved.
Do not overload the tires by exceeding the
specified load limit. The maximum permis-
sible load can be found on the vehicle's Tire
and Loading Information placard on the
B-pillar on the driver's side (
Ypage 185).
iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
DOT, Tire Identification Number (TIN)
U.S tire regulations prescribe that every tire
manufacturer or retreader must imprint a TIN
in or on the sidewall of every tire produced.
The TIN is a unique identification number.
The TIN enables the tire manufacturers or
retreaders to inform purchasers of recalls
and other safety-relevant matters. It makes it
possible for the purchaser to easily identify
the affected tires.
The TIN is made up of manufacturer identi-
fication code 0044, tire size0087, tire type
code 0085and manufacturing date 0083.

Rim
This is the part of the wheel on which the tire
is mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicle identification plate on the B-pillar
on the driver's side.
Speed rating
The speed rating is part of the tire identi-
fication. It specifies the speed range for
which the tire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, the spare
wheel, accessories installed, occupants, lug-
gage and the drawbar noseweight, if appli-
cable. The 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 a fully loaded vehicle (the weight of
the vehicle including all accessories, occu-
pants, fuel, luggage and the drawbar nose-
weight, 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:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1 psi. Another unit for tire pressure
is bar. 100 kilopascals (kPa) are the equiva-
lent of 1 bar.
Load index
In addition to the load-bearing index, the
load index may also be imprinted on the side-
wall of the tire. This specifies the load-
bearing capacity more precisely.
Curb weight
The weight of a vehicle with standard equip-
ment including the maximum capacity of fuel,
oil and coolant. It also includes the air-con-
ditioning 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 is the maximum per-
missible weight in kilograms or pounds 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 square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire'ssurface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the
tires out of direct sunlight for at least
three hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km)

Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a
risk of hydroplaning. These advantages can
only be gained if the tires are fitted corre-
sponding to the direction of rotation.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
XMake sure that you have the appropriate
tire-changing tools. For further informa-
tion inquire at any smart center.
XStop the vehicle on solid, non-slippery and
level ground.
XApply the parking brake (Ypage 101).
XBring the front wheels into the straight-
ahead position.
XVehicles with automatic transmission:
shift the transmission to position P.
XVehicles with manual transmission:
depress the clutch pedal fully and engage
first or reverse gear.
XSwitch off the engine.
XRemove the SmartKey from the ignition
lock.
XAlso secure the vehicle against rolling
away.
Securing the vehicle to prevent it from
rolling away
XOn level ground:place chocks or other suit-
able items under the front and rear of the
wheel that is diagonally opposite the wheel
you wish to change.
XOn light downhill gradients: place chocks
or other suitable items in front of the
wheels of the front and rear axle.
Raising the vehicle
GWARNING
If you do not position the jack correctly at
the appropriate jacking point of the vehi- cle, the jack could tip over with the vehicle
raised. There is a risk of injury.
Only position the jack at the appropriate
jacking point of the vehicle. The base of the jack must be positioned vertically,
directly under the jacking point of the
vehicle.
