R
Optionally, tires with a maximum speed of
ove r149 mph (240km/h) may have "ZR" in
the size description, depending on the
manufacturer (e.g. 245/40 ZR 18).
The service specification is made up of
load-bearing index 0023and speed rating
0024.
R If the size description of you rtire includes
"ZR" and there are no service
specifications, ask the tire manufacturer in
order to find out the maximum speed.
If a service specification is available, the
maximum speed is limited according to the
speed rating in the service specification.
Example: 245/40 ZR 18 97 Y. In this
example, "97 Y" is the service specification.
The letter "Y" represents the speed rating
and the maximum speed of the tire is
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: 275/40 ZR 18 (99 Y).
The speed rating "(Y)" indicates that the
maximum speed of the tire is over 186mph
(300km/h). Ask the tire manufacturer
about the maximum speed. All-weather tires and winter tires

Not all tires with the M+S marking provide
the driving characteristics of winter tires.
In additio nto the M+S marking, winter tires
also have the 0001snowflake symbol on
the tire wall. Tires with this marking fulfill
the requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC)
regarding snow traction, and were specially
developed for driving on snow.
An electronic speed limiter prevents your
vehicle from exceeding the following speeds:
R 130 mph (210 km/h):
-all vehicles (except AMG vehicles)
R 155 mph (250 km/h)
-S 63 AMG
- S 65 AMG
R 186 mph (300 km/h)
-S 63 AMG (Performanc ePackage)
- S63A MG with increased top speed
- S65A MG with increased top speed
The speed rating of tires mounted at the
factory may be higher than the maximum
speed that the electronic speed limiter
permits.

Tire labelingWheels and tires

Make sure that your tires have the required
speed rating for your vehicle as specified in
the "Tires" section (Y page 521), e.g. if you
buy new tires.
Further information about reading tire data
can be obtained from any qualified specialist
workshop. Load index
i
Tire data is vehicle-specific and may
deviate from the data in the example.
In addition to the load bearing index, load
index 0002may be imprinted after the letters
that identify speed rating 0024(Ypage 515) on
the sidewall of the tire.
R If no specification is given: no text (as in the
example above), represents astandard
load (SL) tire
R XL or Extra Load: represents a reinforced
tire
R Ligh tload: represents a light load tire
R C, 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)
U.S. tire regulations prescribe that every
manufacturer of new tires or retreader has to
imprint a TIN in or on the sidewall of each tire
produced. The TIN is a unique identification number. The
TIN enables the tire manufacturers 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
identification code
0003, tire size0026, tire type
code 0025and manufacturing date 0023.
i Tire data is vehicle-specific and may
deviate from the data in the example.
DOT (Department of Transportation): tire
symbol 0002indicates that the tire complies
with the requirements of the U.S. Department
of Transportation.
Manufacturer identification code:
manufacturer identification code 0003provides
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
(Y page 498).
Tire size: identifier0026describes the tire size.
Tire type code: tire type code0025can be
used by the manufacturer as a code to
describe specific characteristics of the tire.
Date of manufacture: date of manufacture
0023 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. Tire labeling

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:
R if the vehicle has been parked without
direct sunligh tonthe tires for at least three
hours and
R if the vehicle has not been driven more 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 lb). 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 identification 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 of 0008in
(1.6 mm) has been reached. Occupant distribution
The distribution of occupants in a vehicle at
their designated seating positions. Total load limit
Rated cargo and luggage load plus
68 kilograms (150 lb), multiplied by the
vehicle's designated seating capacity. 520
Definition of terms for tires and loadingWheels and tires

Mercedes-Ben
zspecifically for your
vehicle.
These tires have been specially adapted for
use with the control systems, such as ABS
or ESP ®
, and are marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-BenzO riginal Extended
(tires featuring run-flat characteristics)
R MO1 =Mercedes-Benz Original (only
certain AMG tires)
Mercedes-BenzO riginal Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
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.
i The recommended pressures for various
operating conditions can be found:
R on the Tire and Loading Information
placard with the recommende dtire
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 501).
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.
i Notes on the vehicle equipmen t–always
equip the vehicle with:
R tires of the same size on a given axle
(left/right)
R the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
