Do not exceed the permissible maxi‐
mum speed of the MOEx tended tyres. #
Avoid any abrupt steering and driving
manoeuvres as well as driving over
obs tacles (kerbs, pot holes, off-road).

These tyres are specially adap tedto the

R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(run-flat tyres only for cer tain wheels)
R MO1 = Mercedes-Benz Original (only cer‐
tain AMG tyres)
Otherwise, cer tain properties, such as han‐
dling characteristics, vehicle noise emis‐
sions, consum ption, etc. could be ad versely
af fected. Furthermore, other tyre sizes could
re sult in the tyres rubbing against the body
and axle components when loaded. This
could result in damage tothe tyre or the

that
ha ve been checked and recommended by
Mercedes-Benz. *

Only inter change the front and rear
wheels if the wheels and tyres ha vethe

The wear pat tern s on the front and rear wheels
dif fer:
R front wheels wear more on the tyre shoulder
R rear wheels wear more in the cent reofthe
tyre
Do not drive wi thtyres that ha vetoo little tread

ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
