PSI (pounds per squareinch)
Astandard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and
Rif the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, aroof rack or ahigh-per-
formanceb attery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number)
This is aunique identifier which can be used by
at ire manufacturer to identify tires, for example
for aproduct recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date.
Load bearing index
The load bearing index (also load index) is acode
that contains the maximum load bearing capa-
city of atire.
Traction
Traction is the result of friction between the tires
and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Occupant distribution
The distribution of occupants in avehicle at their
designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(15 0lbs)m ultiplied by the number of seats in
the vehicle.
Changing awheel
Flat tire
The "Breakdown assistance" section
(Ypage 271) contains information and notes on
how to deal with aflat tire. Information on driv-
ing with MOExtended tires in the event of aflat
tire can be found under "MOExtended tires (tires
with run-flat characteristics" (
Ypage 271).
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 wheel brakes or suspension components
may also be damaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equippedw ithatire pressure
monitor ,electronic components are located
in the wheel.

General notes
You can ask for information regarding permitted
wheel/tire combinations at an authorized
Mercedes-Benz Center.
You should regularl ycheck the pressure of the
emergency spare wheel, particularly priort o
long trips, and correct the pressure as neces-
sary (
Ypag e290). The valu eonthe wheel is
valid.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz
specifically for you rvehicle.
These tires have been speciall yadapted for
use with the control systems, such as ABS or
ESP
®,a nd are marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-fla tcharacteristics)
RMO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be use donwheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehiclen oise
emissions or fuel consumption, may other-
wis ebea dversely affected .Inaddition, when
driving with aload, tire dimension variations
coul dcaus ethe tires to come into contact
with the bodywork and axle components. This
coul dresult 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.
Informatio nontires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
!Retreaded tires are neither tested nor rec-
ommendedbyM ercedes-Benz, since previ-
ous damage cannot alway sbedetected on
retreaded tires. As aresult, Mercedes-Benz
cannot guarantee vehicles afety if retreaded
tires are mounted .Donot mount use dtires if
you have no information abo ut thei
r previous
usage. The recommendedp
ressures for various oper-
ating conditions can be found:

Observe the notes on recommendedt ire pres-
sure sunder various operating conditions
(
Ypag e290).
Check tire pressures regularly,a nd only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicled ocument wallet.
Notes on the vehiclee quipment–alway sequip
the vehicle:
Rwith tires of the same size on agivena xle (left
and right)
Rwith the same type of tire (summer tires,
MOExtended tires, winter tires)
Exception: it is permissible to instal ladiffer-
ent type or make in the event of aflat tire.
Observe the "MOExtended tires (tires with
run-fla tcharacteristics" section (
Ypag e271).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory.I t
is therefore recommendedt hat you additionally
equip you rvehiclew ithaTIREFIT kit if you mount
tires that do not feature run-fla tproperties, e.g.
winter tires. ATIREFIT kit may be obtained from
aq ualified specialist workshop.
