419 Technical data
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 placard with
the recommended tire inflation
pressures is located on the driver’s
door B-pillar. Some vehicles may have
supplemental tire inflation pressure
information for driving at high speeds
(page 310) 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.
