Rims and tires
!
Only use tires which have been tested
and approved by Mercedes-Benz. Tires
approved by Mercedes-Benz are devel-
oped to provide best possible perfor-
mance in conjunction with the driving
safety systems on your vehicle such as
ABS or ESP
®. Tires specially developed
for your vehicle and tested and ap-
proved by Mercedes-Benz can be iden-
tified by finding the following on the
tire’s sidewall:
MO = M

AMG vehicles:
Does not apply to all approved tires
on AMG vehicles. For information
on tested and approved tires for
AMG vehicles, contact an autho-
rized Mercedes-Benz Center.

Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.iFor information on driving with
MOExtended tires, see
“MOExtendedsystem*” (
page 321).
!Using tires other than those approved
by Mercedes-Benz can have detrimen-
tal effects, such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.

450 Technical dataRims and tires
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar. Some vehicles may have sup-
plemental tire inflation pressure infor-
mation for driving at high speeds
(page 312) or for vehicle loads less
than the maximum loaded vehicle con-
dition. If such information is provided,
it can be found on the placard located
on the inside of the fuel filler flap. The
tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance recom-
mendation included with vehicle.
iThe following pages also list the ap-
proved wheel rim and tire sizes for
equipping your vehicles with winter
tires. Winter tires are not available as
standard or optional factory equip-
ment, but can be purchased from an
authorized Mercedes-Benz Center.
Depending on vehicle model and the
standard or optional factory-equipped
wheel rim/tire configuration on your
vehicle (Appearance Package, Sport
Package etc.), equipping your vehicle
with winter tires approved for your ve-
hicle model may also require the pur-
chase of two or four wheel rims of the
recommended size for use with these
winter tires. See an authorized
Mercedes-Benz Center for more infor-
mation.
