Rims and tires
!Only use tires which have been tested and
approved for your vehicle by Mercedes-Benz.
Tires approved by Mercedes-Benz are developed
to provide best possible performance in conjunc-
tion with the driving safety systems on your vehi-
cle such as ABS or ESP
®. Tires specially
developed for your vehicle and tested and ap-
proved by Mercedes-Benz can be identified by
finding the following on the tire’s sidewall:

MO = Mercedes-Benz Original equipment
tires

MOE = Mercedes-Benz Original Extended
(tires with limited run-flat characteristics)
original equipment tires. Using tires other
than those approved by Mercedes-Benz may
result in damage that is not covered by the
Mercedes-Benz Limited Warranty.
iFor information on driving with MOExtended
tires, see “MOExtended system*” (
page 326).
!Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as

poor handling characteristics

increased noise

increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the
result.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz Cen-
ter. A placard with the recommended tire infla-
tion pressures is located on the driver’s door
B-pillar. Some vehicles may have supplemental
tire inflation pressure information for driving at
high speeds (
page 322) or for vehicle loads
less than the maximum loaded vehicle condition
(
page 321).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 mainte-
nance recommendation included with vehicle.
iThe following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration 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 in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the spare wheel rim.
If the tire inflation pressure on the yellow 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
pressure given on the yellow label on the spare
wheel rim.
iPlease note that the tire inflation pressure of
the Minispare tire differs from the tire inflation
pressure of the road tires.
Make sure the Minispare tire is inflated to ap-
proximately 61 psi (4.2 bar).
