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
ercedes-Benz O
riginal
equipment tires
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.


MOE = M

E
xtended (tires with limited run-flat
characteristics) original equipment
tires
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 345).
!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.

472 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 340) or for vehicle loads less
than the maximum loaded vehicle con-
dition (
page 339). If such information
is provided, it can be found on the plac-
ard located on the inside of the fuel fill-
er flap. The tire inflation pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation 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
vehicle model may also require the
purchase of two or four wheel rims of
the recommended size for use with
these winter tires. See an authorized
Mercedes-Benz Center for more
information.

!Please compare the recommended tire
inflation pressure for your vehicle with
the tire inflation pressure on the yellow
label located on the spare wheel rim.
If the tire inflation pressure on the yel-
low label on the spare wheel rim differs
from the values given in this Operator’s
Manual, inflate the spare wheel tire to
the recommended tire inflation pres-
sure given on the yellow label on the
spare wheel rim.
iPlease note that the tire inflation pres-
sure of the Minispare tire differs from
the tire inflation pressure of the road
tires.
Make sure the Minispare tire is inflated
to approximately 60 psi (4.1 bar).
