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 Center.
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 414).
!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 
dimensional variations and different tire defor-
mation 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. Some vehicles may have supplemental 
tire inflation pressure information for driving at 
high speeds (
page 313) or for vehicle loads 
less than the maximum loaded vehicle condition 
(
page 313). If such information is provided, it 
can be found on the placard located on the in-
side 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 
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 (Performance 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 authorized 
Mercedes-Benz Center for more information.
