Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz .C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with al oad, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components .T his
could result in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Information on tires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz ,s ince previ-
ous damage cannot alway sbed etected on
retreaded tires. As ar esult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded

Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in

Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefor er ecommended that you additionally
