These tires have been specially adapted for
use with the control systems, such as ABS or
ESP
®,and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
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 aload, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components .This
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 alwaysbed etected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found:
Ron the Tire and Loading Information placard
on the B-pillar on the driver's side
Rin the tire pressure table on the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
(
Ypage 263).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet. Notes on the vehicle equipment
–alwayse quip
the vehicle:
Rwith tires of the same size on agiven axle (left
and right)
Rwith the same type of tires at agiven time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to mount adiffer-
ent type or make in the event of aflat tire.
Observe t

he "MOExtended tires (tires with
run-flat characteristics)" section
(
Ypage 247).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefor erecommended that you additionally
equip your vehicle with aTIREFIT kit if you mount
tires that do not feature run-flat characteristics,
e.g. winter tires. ATIREFIT kit may be obtained
from aqualified specialist workshop.

Important safety notes
GWARNING
The wheel or tire size as well as the tire type of the spare wheel or emergencys pare wheel
and the wheel to be replaced may differ.
Mountin ganemergencys pare wheel may
severely impair the driving characteristics.
There is arisk of an accident.
To avoid hazardous situations:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergencys pare wheel that differs in size.
Ronly useaspare wheel or emergencys pare
wheel of adifferent size briefly.
Rdo not switch ESP®off.
Rhave aspare wheel or emergencys pare
wheel of adifferent size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergencys pare wheel or spare
wheel of adifferent size, you must not exceed
the maximum speed of 50 mph (80 km/h).
