Rims and Tires
Rims and Tires
Use only 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, ex-
hibit dimensional variations and differ-
ent 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 tire inflation
pressure table is located on the fuel fill-
er flap of the vehicle. The tire pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.
