422 Technical dataRims and tiresOnly use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims 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 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 pressure information for
driving at high speeds (
page 289) or
for vehicle loads less than the maxi-
mum loaded vehicle condition. 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 main-
tenance recommendation included
with vehicle.
