All-weather tires and winter tires
Index Speed rating
Q M+S 2 up to 100 mph (160 km/h)
T M+S 2 up to 118 mph (190 km/h)
H M+S 2 up to 130mph (210 km/h)
V M+S 2 up to 149 mph (240 km/h)
i Not all tires with the M+S marking provide
the driving characteristics of winter tires.
In addition to the M+S marking, winter tires
also have the i snowflake 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 the tire traction on snow. They
have been especially developed for driving
on snow.
An electronic speed limiter prevents your
vehicle from exceeding the following speeds:
R
all vehicles (except AMG vehicles):
130 mph (210 km/h)
R
AMG vehicles: 155 mph (250 km/h)
R
AMG vehicles with increased top speed:
174 mph (280 km/h)
R
The speed rating of tires mounted at the
factory may be higher 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 in the "Tires" section (
Y page 426).
Further information about reading tire data
can be obtained from any qualified specialist
workshop.
Load index
In addition to the load bearing index, load
index : may be imprinted after the letters
that identify the speed index B on the
sidewall of the tire (
Y page 415).
R
If no specification is given: no text (as in the
example above), represents a standard
load (SL) tire
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
i Tire data is vehicle-specific and may
deviate from the data in the example.
Maximum load rating
Maximum tire load : is the maximum
permissible weight for which the tire is
approved.
