Quality grades can be found,where applicable,
on the tire sidewall between tread shoulde rand

Example:
RTreadwear grade: 200
RTractiongrade: AA
RTemperature grade: A
All passengerc ar tires must conform to the stat-
utory safety requirements in additio ntothese
grades.
iThe actua lvalues for tires are vehicle-spe-
cific and may deviate from the values in the
illustration.
Treadwear
The treadwea rgrad eisac omparativ erating
based on the wea rrate of the tire whe ntested
unde rcontrolled conditions on aspecified U.S.
government course. For example, atire graded
150 would wea rone and one-half times as well
on the government test track as atire graded
100.
The relative performance of tires depends upon
the actua lconditions of their use ,however, and
may depart significantly from the norm duet o
variations in driving habits, service practices
and differences in road characteristics and cli-
mate.
Traction
GWARNING
The tractio ngrad eassigne dtothis tire is
based on straight-ahead braking traction
tests, and doesn ot include acceleration, cor-
nering, hydroplaning ,orpeaktractio nchar-
acteristics.
!Avoid wheelspin. Thisc an leadtodamage to
the driv etrain.
The tractio ngrades –from highest to lowest –
are AA, A, Band C. Thoseg rades represent the
tire's ability to stop on wet pavement as meas-
ure dunde rcontrolled conditions on specified
government test surfaces of asphal tand con-
crete. Atire marked Cmay have poort raction
performance.
The safe speedonaw et, snow coveredoricy
road is always lower than on dry road surfaces. You should pay speciala
ttentiontoroadc ondi-
tions whe ntemperatures are around freezing
point.
Mercedes-Benz recommends aminimum tread
depth of ãin (4 mm )onallfour winter tires.
Observe the legally required minimum tire tread
depth (
Ypag e256). Winter tires can reduce the
braking distance on snow-covered surfaces in
compariso nwiths ummer tires. The braking dis-
tance is stil lmuch furthe rthan on surfaces that
are not icy or coveredw iths now. Take appro-
priate care whe ndriving.
Temperature
GWARNING
The temperature grad efor this tire is estab-
lished for atire that is properly inflated and
not overloaded. Excessiv espeed, underinfla-
tion, or excessive loading ,eithe rseparately or
in combination, can cause excessive heat
build-up and possibl etire failure.
The temperature grades are A(the highest),B ,
and C, representing the tire's resistance to the
generation of heata nd its ability to dissipate
heatw hent ested unde rcontrolled conditions
on aspecified indoor laboratory test wheel. Sus-
taine dhight emperature can cause the material
of the tire to degenerate and reduce tire life, and

Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The whee lbrakes or suspension components
may als obedamaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with atire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be use dnear
the valve .This coul ddamage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Always pay attention to the instructions and
safety notes when changing awheel
(
Ypag e275).
The wea rpatterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclearw earp attern
has formed on the tires. Front tires typically
wea rmore on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the interval sinthe tire manufacturer's
warranty book in you rvehicl edocuments. If no
warranty book is available,t he tires should be
rotated every 3,000 to 6,000 mile s(5,000 to
10,000 km) .Depending on tire wear, this may
be required earlier. Do not change the direction
of whee lrotation.
Clean the contact surfaces of the whee land the
brake disc thoroughly every time awhee lisr ota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system or
the tire pressure monitor.
Directio nofrotation
Tires with aspecified direction of rotation have
additiona lbenefits, e.g. if there is arisk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.

GWARNING
Oiled or greased wheel bolts or damaged

lose awheel while driving. There is arisk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact aqualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is arisk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instruction sand
safety notes in the "Changing awheel" section
(
Ypage 274).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective
wheel.
!To prevent damage to the paintwork ,hold
the wheel securely against the wheel hub

These tires have been specially adapted for
use with the control systems, such as ABS or

®,and are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended

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:

Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefor erecommended that you additionally
