Rims and tires
!
Only use tires which have been specifi-
cally developed for your vehicle and 
tested and approved by 
Mercedes-Benz. Tires approved by 
Mercedes-Benz are developed to pro-
vide best possible performance in con-
junction 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 side-
wall:
MO = M
ercedes-Benz O
riginal 
equipment tires
MOE = M
ercedes-Benz O
riginal 
E
xtended (tires with limited run-flat 
characteristics) original equipment 
tires
Using tires other than those approved 
by Mercedes-Benz may result in dam-
age that is not covered by the 
Mercedes-Benz Limited Warranty.
iFor information on driving with 
MOExtended tires*, see 
“MOExtendedsystem” (
page 312).
!Using tires other than those approved 
by Mercedes-Benz can have detrimen-
tal 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 dif-
ferent tire deformation characteristics 
that could cause them to come into 
contact with the vehicle body or axle 
parts. Damage to the tires or the vehi-
cle 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 pres-
sures is located on the driver’s door 
B-pillar. Some vehicles may have sup-
plemental tire inflation pressure infor-
mation for driving at high speeds 
(page 307) or for vehicle loads less 
than the maximum loaded vehicle con-
dition. 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 recom-
mendation included with vehicle.
