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. This may result in damage to the
tires or the vehicle.
iFurther information on tires and rims is
available at any authorized Mercedes-
Benz Center. A tire inflation pressure
table is located on the fuel filler flap of
the vehicle. The tire pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire man-
ufacturer’s maintenance recommenda-
tion included with vehicle.
