Rims and tires
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
vehicle such as ABS or ESP
®. Tires specially
developed for your vehicle and tested and
approved by Mercedes-Benz can be identified by
finding the following on the tire’s sidewall:

MO = Mercedes-Benz 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.
!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
Center. A placard with the recommended tire
inflation pressures is located on the driver’s door
B-pillar (
page 334). Some vehicles may have
supplemental tire inflation pressure information
for driving at high speeds (
page 340) or for
vehicle loads less than the maximum loaded
vehicle condition (
page 348). If such informa-
tion is provided, it can be found on the tire infla-
tion label 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
recommendation included with vehicle.
iThe following pages also list the approved
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. Contact an autho-
rized Mercedes-Benz Center for more informa-
tion.
