2011 MERCEDES-BENZ R-Class winter tires

For further information on the load bearing
index, see load index ( Y page 339).
Speed index: speed index B specifies the
approved maximum speed of the tire.GWarning
Even when permitted by law, never operate a
vehicle at speeds greater than the maximum
speed rating of the tires.
Exceeding the maximum speed for which tires
are rated can lead to sudden tire failure,
causing loss of vehicle control and possibly
resulting in an accident and/or serious
personal injury and possible death, for you
and for others.
Regardless of the speed index always observe
the speed limits. Drive carefully and adapt
your driving style to the traffic conditions.

R Optionally, tires with a maximum speed of
over 149 mph (240 km/h) may have "ZR"
in the size description depending on the
manufacturer (e.g. 245/40 ZR 18).
The service specifications consists of load
bearing index A and speed index B.
R If the size description of your tire 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 index in the service specification.
Example: 245/40 ZR18 97 Y. In this
example, "97Y" is the service specification.
The letter "Y" represents the speed index
and the maximum speed of the tire is
limited to 186 mph (300 km/h).
R Every tire that has a maximum speed above
186 mph (300 km/h) must have "ZR" in the
size description and the service
specification must be given in brackets.
Example: 275/40 ZR 18 (99 Y). The speed
index "(Y)" shows that the maximum speed
of the tire is above 186 mph (300 km/h).
Ask the tire manufacturer to find out the
maximum speed.All-weather tires and winter tiresIndexSpeed ratingQ M+S 43up to 100 mph (160 km/h)T M+S43up to 118 mph (190 km/h)H M+S 43up to 130 mph (210 km/h)V M+S43up to 149 mph (240 km/h)

Not all tires that have the M+S
identification offer the driving
characteristics of winter tires. Winter tires
have, in addition to the M+S identification,
the i snow flake symbol on the tire
sidewall. Tires with this identification fulfill
the requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC)
regarding the tire traction on snow and
43 or M+S i for winter tires.338Tire labelingTires and wheels

Points to remember
GWarning
Observe the "Important safety information"
( Y page 320).
! For safety reasons, Mercedes-Benz
recommends that you only use tires,
wheels and accessories which have been
approved by Mercedes-Benz specifically
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-Benz Original
R MOE = Mercedes-Benz Original Extended
(tires with run-flat characteristics)
R MO1 = Mercedes-Benz Original (AMG)
Only use Mercedes-Benz Original Extended
tires on wheels that have been specifically
approved by Mercedes-Benz.
If you use other tires, wheels and
accessories, Mercedes-Benz cannot
accept any responsibility for damage that
may result from this. Further information
about tires, wheels and approved
combinations can be obtained from any
authorized Mercedes-Benz Center.
! If you mount tires other than those tested
and recommended by Mercedes-Benz,
characteristics such as handling, noise
levels and fuel consumption, etc. may be
adversely affected. In addition, when
driving with a load, tire dimensional
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.
i Further information about tires and
wheels can be obtained from any
authorized Mercedes-Benz Center.
i The Tire and Load Information placard
with the recommended tire pressures is
attached to the B-pillar on the driver's side.
Further information about driving at high
speeds or driving with vehicle loads that are
lighter than the maximum vehicle load can
be found in the tire pressure table on the
inside of the fuel filler flap. 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.
Further information on the recommended tire
inflation pressure and on tire pressures for
specific driving conditions, see (Y page 322).
i Notes on the vehicle equipment:
R always mount tires of the same size on a
given axle (left/right).
R always mount the same type of tires on
your vehicle at a given time (summer
tires, winter tires, MOExtended tires).
i Vehicles featuring the MOExtended run-
flat system are not equipped with a TIREFIT
kit.
It is therefore recommended that you
additionally equip your vehicle with the
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit is available from any qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
i The following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle with winter tires.

as standard equipment or as an optional
extra.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size, as the size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the
equipment installed at the factory.
Tires, wheel rims and further information
can be obtained at a qualified specialist
workshop, e.g. an authorized Mercedes-
Benz Center.344Wheel/tire combinationsTires and wheels
