2015 MERCEDES-BENZ C-Class COUPE tire type

M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
00CF in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than 00CFin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use win-
ter tires or all-season tires. Both types of tire are identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. These tires have
been developed specifically for driving in
snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted M+S tires:
X Check the tire pressures (Y page 309).
X Restart the tire pressure monitor
(Y page 309).
For more information on driving with the
emergency spare wheel, see (Y page 338).Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident. To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
! Vehicles with steel wheels:
if you
mount snow chains on steel wheels, you
may damage the hub caps. Remove the hub caps from the relevant wheels before
mounting the snow chains.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding standard of quality.
If you intend to mount snow chains, please
bear the following points in mind:
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (Y page 329).
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi-
ble when you come to a road that is not
snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You may wish to deactivate ESP ®
(Y page 66) when pulling away with snow
chains installed. You can thereby allow the wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).

WARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair the steering and driving characteristics and lead
to brake failure. There is a risk of accident.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load.
Two instruction labels on your vehicle show
the maximum possible load.
(1) The Tire and Loading Information placard is on the B-pillar on the driver's side. The
Tire and Loading Information placard
shows the maximum permissible number
of occupants and the maximum permis-
sible vehicle load. It also contains details
of the tire sizes and corresponding pres-
sures for tires mounted at the factory.

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 descrip-
tion (as shown above): these are passenger
vehicle tires according to European manufac-
turing 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. manu-
facturing 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 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" 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 man-
ufacturer (e.g. 245/40 ZR 18).
Rim diameter: rim diameter0085is the diam-
eter of the bead seat, not the diameter of the
rim flange. The rim diameter is specified in
inches (in).
Load-bearing index: load-bearing index0083
is a numerical code that specifies the maxi-
mum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum permissi-
ble load can be found on the vehicle's Tire and Loading Information placard on the B-pillar on
the driver's side (Y page 312).
Example:
Load-bearing index 91 indicates a maximum
load of 1,356 lb (615 kg) that the tires can
bear. For further information on the maximum
tire load in kilograms and lbs, see
(Y page 316).
For further information on the load bearing
index, see "Load index" (Y page 321).
Speed rating: speed rating0084specifies the
approved maximum speed of the tire. G
WARNING
Exceeding the stated tire load-bearing capa-
city 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 Tire labeling

Tire data is vehicle-specific and may devi-
ate from the data in the example.
In addition to the load-bearing index, load
index 0043may be imprinted after the letters
that identify speed rating 0084(Ypage 319) on
the sidewall of the tire.
R If no specification is given: no text (as in the

R XL or Extra Load: represents a reinforced
tire
R Light Load: 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 tire manufacturers to inform pur-
chasers of recalls and other safety-relevant
matters. It makes it possible for the pur-
chaser to easily identify the affected tires.
The TIN is made up of manufacturer identifi-
cation code 0044, tire size0087, tire type code 0085
and manufacturing date 0083.
i Tire data is vehicle-specific and may devi-
ate from the data in the example.
DOT (Department of Transportation): tire
symbol 0043indicates that the tire complies
with the requirements of the U.S. Department
of Transportation.
Manufacturer identification code: manu-
facturer identification code 0044provides
details on the tire manufacturer. New tires
have a code with two symbols. Retreaded
tires have a code with four symbols.
For further information about retreaded tires,
see (Y page 302).
Tire size: identifier0087describes the tire size.
Tire type code: tire type code0085can be used
by the manufacturer as a code to describe
specific characteristics of the tire.
Date of manufacture: date of manufacture
0083 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.

ards
A uniform standard to grade the quality of
tires with regards to tread quality, tire traction and temperature characteristics. Ratings are determined by tire manufacturers using U.S.
government testing procedures. The ratings
are molded into the sidewall of the tire. Recommended tire pressure
The recommended tire pressure applies to
the tires mounted at the factory.
The Tire and Loading Information placard con-
tains the recommended tire pressures for
cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed.
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions. Increased vehicle weight due to

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 sunlight on the tires for at least three
hours and
R if the vehicle has not been driven further
than 1 mile (1.6 km) Tread

bead. Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts 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 accesso-
ries.
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

Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tire dimen-
sion variations could cause the tires to
come into contact with the bodywork and
axle components. This could result in dam- age 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 tes-
ted and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
Overview of abbreviations used in the follow- ing tire tables:
R BA: both axles
R FA: front axle
R RA: rear axle
The recommended pressures for various
operating conditions can be found:
R on the Tire and Loading Information placard
with the recommended tire 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 306).
Check tire pressures regularly, and only when the tires are cold. Comply with the mainte-
nance recommendations of the tire manufac-
turer in the vehicle document wallet. Notes on the vehicle equipment – 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 (sum-
mer tires, winter tires, MOExtended tires)
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Y page 287).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qualified specialist work-
shop.
i Not all wheel and tire combinations are
available at the factory for all countries.
i The following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle 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
dependent on the model and the equip-
ment installed at the factory.
The tires and wheel rims, as well as further information, can be obtained at a qualified
specialist workshop. 330
