vehicle-specific and may differ from that in
the illustration. You can find the valid
maximum
permissible
gross vehicle weight
rating for your vehicle on the Tire and
Loading Information placard. X
The Tire and Loading Information placard
gives you details on maximum permissible
gross vehicle weight rating :: "The gross
weight of occupants and luggage must
never exceed XXX kilograms or XXX
pounds."
The gross weight of all vehicle occupants,
cargo, luggage

and trailer load/noseweight (if
applicable) must not exceed the specified
value. Number of seats
i The specifications shown on the Tire and
Loading Information placard in the
illustration are examples. The number of
seats is

vehicle-specific and can differ from
the details shown. The number of seats in
your vehicle can be found on the Tire and
Loading Information placard. Maximum number of seats
: determines
the
maximum number of occupants allowed to
travel in the vehicle. This information can be
found on the Tire and Loading Information
placard. Determining the correct load limit
Step-by-step instructions The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575
pursuant to the "National Traffic and Motor
Vehicle Safety Act of 1966".
X
Step 1: Locate the statement "The
combined weight of occupants and cargo
should never

exceed XXX kg or XXX lbs." on
your vehicle’s Tire and Loading Information
placard.
X Step 2: Determine the combined weight of
the
driver and passengers that will be riding
in your vehicle.
X Step 3: Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX lbs.
X Step 4: The resulting figure equals the
available amount

of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400 lbs and there will be five 150
lbs passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs (1400 - 750 (5 x 150) =
650 lbs). Loading the vehicle

X
Step 5: Determine the combined weight of
luggage and cargo being loaded on the
vehicle.
That weight may not safely exceed
the available cargo and luggage load
capacity calculated in step 4.
X Step 6 (if applicable): If your vehicle will
be towing a trailer, load from your trailer
will be transferred to your vehicle. Consult
this manual

to determine how this reduces
the available cargo and luggage load
capacity of your vehicle ( Y page 256).254

the tire's ability to stop on a wet surface as
measured under controlled conditions on
specified
government
test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance. G
WARNING
If ice has formed on the road, tire traction will
be substantially

reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road
surfaces.
You should pay special attention to road
conditions when temperatures are around
the freezing point.
Mercedes-Benz recommends a minimum
tread depth of 1
/ 6 in (4 mm) for all four winter
tires ( Y page 244) to maintain normal driving
characteristics in winter. Winter tires can
reduce the braking distance on snow covered
surfaces in comparison to summer tires. The
braking distance is still much further than on
surfaces that are not icy or covered with
snow. Take appropriate care when driving.
! Avoid wheelspin. This can lead to damage
to the drive train. Temperature
G
WARNING
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
excessive heat build-up and possible tire
failure.
The temperature grades are A (the highest),
B, and C, These represent the tire's
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory test wheel. Sustained high
temperature
can

cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade C corresponds to a level
of performance which all passenger car tires
must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law. Tire labeling

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
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 width : shows the nominal
tire width in millimeters.
Nominal aspect

ratio: aspect ratio ; is the
ratio between the tire height and tire width
and is shown as a percentage. The aspect
ratio is calculated by dividing the tire width by
the tire height.
Tire code: tire code = specifies the tire type.
"R" represents radial tires. "D" represents
diagonal tires, "B" represents diagonal radial
tires.
Optionally, tires with a maximum speed of
over 149 mph (240 km/h) may have "ZR" in
the size description depending on the
manufacturer (e.g. 245/40 ZR 18).
Rim diameter: rim diameter ? is 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 index A
is a numerical code that specifies the
maximum load-bearing capacity of a tire. G
WARNING
The tire load rating must always be at least
half of the GAWR of your vehicle. Otherwise,
sudden tire failure may be the result which
could cause

an accident and/or serious injury
to you or others.
Always replace rims and tires with rims and
tires having the same specifications
(designation, manufacturer and type) as
shown on the original part. G
WARNING
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar . Overloading the tires
can overheat them, possibly causing a
blowout.

Overloading the tires can also result
in handling or steering problems, or brake
failure. Tire labeling

Increased vehicle weight due to
optional equipment
This is the combined weight of all standard
and optional equipment available for the
vehicle, regardless of whether it is actually
installed on the vehicle or not. Wheel 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 index
The speed index is part of the tire
identification. It

specifies the speed range for
which the tire is approved. GTW (Gross Trailer Weight)
The GTW is the sum of the weight of a trailer
and the weight of the load, luggage,
accessories etc. on the trailer. GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, the spare
wheel, accessories installed, occupants,
luggage and the drawbar noseweight if
applicable. 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 permitted gross
weight of

the fully laden vehicle (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
weight of the laden vehicle
The maximum weight is the sum of the curb
weight of the vehicle, the weight of the
accessories, the maximum load and the
weight of

the optional equipment installed at
the factory. Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa is the
equivalent of 1 psi

. Another unit for tire
pressure is bar. 100 kilopascal (kPa) is the
equivalent of 1 bar. Load index
In addition

to the load bearing index, the load
index may also be imprinted on the sidewall
of the tire. This specifies the load bearing
capacity more precisely. Curb weight
The weight of a vehicle with standard
equipment, including the maximum capacity
of fuel, oil and coolant and also includes the
air-conditioning system and optional
equipment if these are installed on the
vehicle, but does not include passengers or
luggage. Definition of terms for tires and loading
263Wheels and tires Z

Maximum tire load
The maximum tire load is the maximum
permissible weight in kilograms or lbs 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)
Standard unit of measurement 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 every square inch of the
tire's surface.

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. For this,
the vehicle must have been stationary for at
least 3 hours or not have traveled more than
1.6 km (1 mile) in this time. Tire tread
The part of the tire that comes into contact
with the road. Tire 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
tire 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, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the
accessories. TIN (Tire Identification Number)
This is a unique identification number which
can be

used by a tire manufacturer to identify
tires, for example for a product 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 a tire. Traction
Traction is the result of friction between the
tires and the road surface. 264
