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
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 pressures is located on the driver’s 
door B-pillar (
page 366). Some vehicles may 
have supplemental tire inflation pressure infor-
mation for driving at high speeds (
page 372) 
or for vehicle loads less than the maximum 
loaded vehicle condition (
page 372). 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 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 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. Contact an 
authorized Mercedes-Benz Light Truck Center 
for more information.
