General:depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letters or may contain
one letterthat 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 widthshows the nominal
tire width in millimeters.
Nominal aspect ratio:aspect ratiois the
size ratio between the tire height and the tire
width and is shown in percent.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 149mph (240km/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
is a numerical code which specifies the
maximum load-bearing capacity of a tire.
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
(Ypage 323).
Example:
Aload-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 (Ypage 327).
For further information on the load-bearing
index, see Load index (Ypage 332).
Speed rating:speed rating specifies the
approved maximum speed of the tire.
GWARNING
Exceeding the stated tire load-bearing
capacity and the approved maximum speed
could lead to tire damage or the tire bursting.
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.
Regardless of the speed rating, always
observe the speed limits. Drive carefully and

Load index
In addition to the load bearing index, load
indexmay be imprinted after the letters
that identify speed index (Ypage 330) on
the sidewall of the tire.
RIf no specificationis given: no text (as in the
example above), representsastandard
load (SL) tire
RXL or Extra Load: represents a reinforced
tire
RLightLoad: 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

DOT, Tire Identification Number (TIN)
Canadiantire regulations prescribe that every
new tire manufacturer or retreader has to
imprintaTIN in or on the sidewall of each tire
produced.
The TIN is a unique identification number. The
TIN makes it easier for tire manufacturers or
retreaders to notify customers of recalls or
other safety-related matters. It makes it
possible for the purchaser to easily identify
the affected tires.
The TIN consists of the manufacturer
identification code, tire size", tire type
code!and manufacturing date.
DOT (Department of Transportation):tire
symbolindicates that the tire complies
with the requirements of the Canadian
Transport Ministry.
Manufacturer identification code:
manufacturer identification codeprovides
details on the tire manufacturer. New tires
have a code with two symbols. Retreaded
tires have a code with four symbols.
Further information about retreaded tires
(Ypage 312).
Tire size:identifier"describes the tire size.
Tire type code:tire type code!can be
used by the manufacturer as a code to
describe specific characteristics of the tire.
Date of manufacture:date of manufacture
provides information about the age of a
tire. The first and second positions represent
the week of manufacture, starting with "01"
for the first calendar week. Positions three
and four represent the year of manufacture.
For example, a tire that is marked with
"3208", was manufactured in week 32 in
2008.

Wheels and tires

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'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.
Tire pressure of cold tires
The tires are cold:
Rif the vehicle has been parked without
direct sunlightonthe tires for at least three
hours and
Rif the vehicle has not been driven further
than 1 mile (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, 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 identifier 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.
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 ofin
(1.6 mm) has been reached.
Occupant distribution
The distribution of occupants in a vehicle 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.

vehicle noise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, tire dimension variations could cause
the tires to come into contact with the
bodywork and axle components. This could
result in damage to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than 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 a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tires are mounted. Do
not mount used tires if you have no
information about their previous usage.
Overview of abbreviations usedinthe
following tire tables:
RBA: both axles
RFA: front axle
RRA: rear axle
The recommended pressures for various
operating conditions can be found:
Ron the Tire and Loading Information placard
with the recommended tire pressures on
the B-pillar on the driver's side
Rin the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions
(Ypage 316).
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:
Rtires of the same size on a given axle (left/
right)
Rthe same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to install a
differenttype or makeinthe event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Ypage 295).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you
additionally equip your vehicle with a TIREFIT
kit if you mount tires that do not feature run-
flat properties, e.g. winter tires.ATIREFIT kit
may be obtained from a qualified specialist
workshop.
iThe following pages contain information
on approved wheel rim and tire sizes for
equipping yourvehicle 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
dependentonthe model and the
equipment installed at the factory.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.
In the following table, the wheel/tire
combinations are assigned to the vehicle
models through variants, e.g. V1, V2 etc.:
