All-weather tires and winter tires
Index Speed rating
H M+S 21 up to 130 mph (210 km/h)
V M+S 21 up to 149 mph (240 km/h)
i Not all tires that have the M+S
identification offer 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 and have been
especially developed for driving on snow.
An electronic speed limiter prevents your
vehicle from exceeding a speed of
130 mph (210 km/h).
The speed index 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 index as specified in the "tires" section
(
Y page 272), e.g. if you buy new tires.
Further information about reading tire data
can be obtained from any qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.
Load identification
i Tire data is vehicle-specific and may
deviate from the data in the example.
In addition to the load bearing index, load
index : may be imprinted after the letters
that identify speed index B(
Y page 263) on
the sidewall of the tire.
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
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.
