ombinations General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be usedonw heels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damag eresulting from the us eoftyres,
wheel soraccessorie sothe rthan those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As aresult,
Mercedes-Ben zcannot guarante evehicle
safety if retreade dtyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels :the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases. Wheel and tyrec
