IndexSpeedrating
Q M+S2up to 100 mph (160 km/h)
T M+S2up to 118 mph (190 km/h)
H M+S2up to 130 mph (210 km/h)
V M+S2up to 149 mph (240 km/h)
iNot all tires with the M+S marking provide
the driv ing characteristics of winter tires. In
addit ion to the M+S marking, winter tires
also have the isnowflake symbol on
the tire wall.Tires with this marking fulfill
the requirements of the Rubber Manufac-
turers Association (RMA) and the Rubber
Association of Canada (RAC) regarding the
tire traction on snow. They have been espe-
cial lydeveloped for driving on snow.
An electronic speed limiter prevents your
veh icle from exceeding the fol lowing speeds:
RAll veh icles (except AMG vehicles):
130 mph (210 km/h)
RAMG veh icles: 155 mph (250 km/h)
RAMG veh icleswit h increased top speed:
174 mph (280 km/h)
The speed rating of tires mounted at the fac- tory may behigher 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 inthe "Tires" section (
Ypage 432).
Further information about reading tire data
can beobtained from any qualified specialist
workshop.
Load index
In addition to the load bearing index, load
index :may beimprinted after the letters
that identify speed index Bon the sidewall of
the tire (
Ypage 421).
RIf no specification isgiven: no text (as inthe
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
depe nds on the maximum load that the tire
can carry at a certain pressure
iTire data isveh icle-specific and may devi-
ate from the data inthe example.

the tire. This specifies the load-bearing capa-
city 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-condi-
tioning 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
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)
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'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.
Cold tire pressure
The ti
res are cold:
Rif the vehicle has been parked without
direct sunlight on the 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
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 manufactu ring d
ate.
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.
TWR (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight that the ball coupling of the trailer tow hitch can support.
