Rims and tires
Rims and tires
!Only use tires which have been tested and
approved by Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to provide best
possible performance in conjunction 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
AMG vehicles:
Does not apply to all approved tires on AMG
vehicles. For information on tested and
approved tires for AMG vehicles, contact an
authorized Mercedes-Benz Light Truck
Center.
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 Light
Truck Center. A placard with the recommended
tire inflation pressure is located on the driver’s
door B-pillar (
page 510). Some vehicles may
have supplemental tire inflation pressure infor-
mation for driving at high speeds (
page 358)
or for vehicle loads less than the maximum
loaded vehicle condition (
page 358). 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
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 Light Truck 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 Light Truck Center for more
information.
