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
Rims and tires
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
under load 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
tire inflation pressure table is located
on the fuel filler cap of the vehicle. The
tire pressure should be checked regu-
larly and should only be adjusted on
cold tires. Follow tire manufacturer’s
maintenance recommendation includ-
ed with vehicle.
