and replace any damaged tires immediately.
Operation281
Wheels and tires
Z

Check wheels and tires for damage at least once
a month. Check wheels and tires afterdriving
off-road or on rough roads. Damaged wheels
can cause a loss of tire pressure. Pay particular
attention to damage such as:
Rcuts inthe tires
Rpunctures
Rtears inthe tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 282). Ifnecessary, turn the
front wheels to full lock inorder to inspect the
inner sideof the tire surface.
All wheels must have a valve cap to protect the valve against dirtand moisture. Do not mount
anything onto the valve other than the standard
valve cap or other valve caps approved by
Mercedes-Benz for your veh icle. Do not use any
other valve caps or systems, e.g. tire pressure
monitoring systems.
Regularly check the pressure of all the tires par-
ticularly prior to long tr ips.Adjust the tire pres-
sure as necessary (
Ypage 284).
Observe the notes on the emergency spare
wheel (
Ypage 304).
The service lifeof tires depends, among other
things, on the foll owing factors:
Rdriving style
Rtire pressure
Rdistance covered
Notes on tire tread
GWAR NING
In suff icient tire tread willreduce tire traction.
The tire isno longer abletodissipat e water.
This means that on wet road surfaces, the risk
of hydroplaning increases, inparticular where
speed isnot adapted to suit the driving con-
dit ions. There isa risk of acc ident.
If the tire pressure istoo high or too low,tires
may exhibit diff erent levelsof wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
widt h of all tires.
Minimum tire tread depth for:
RSummer tires: âin(3 mm)
RM+S tires: ãin(4 mm)
For safety reasons, replace the tires before
the legally prescribe d limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator
(arrow) for tread wear is integrated into the tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are vis ibleonce a tread depth of approx-
imately áin (1.6 mm) has been reached. If this
is the case, the tire isso worn that it must be
replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
Exception: itis permissible to install a differ-
ent type or make in the event of a flat tire.
Observe the "MOExtended tires (tires with
run-flat characteristics" section (
Ypage 266).
ROnly mount tires of the correct size onto the
wheels.
RBreak in new tires at moderate speeds for the
first 60 miles(100 km). They only reach their
full performance after this distance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (
Ypage 304).
282Operation
Wheels and tires

MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tires.
MOExtended tires may only be used in conjunc-
tion with an active tire pressure monitor and
only on wheels specifically tested by Mercedes- Benz.
Notes on driving with MOExtended tires with a
flat tire (
Ypage 266).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit can be obtained from
a qualified specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (
Ypage 299).
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tires. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both types of tire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tires will allow driving safety systems
such as ABS and ESP
®to function optimally in
winter. These tires have been developed specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
XCheck the tire pressures (Ypage 287).
XRestart the tire pressure monitor
(Ypage 287).
For more information on driving with the emer-
gency spare wheel, see (
Ypage 304).
Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
Winter operation283
Wheels and tires
Z

!On some tire sizes there is not enough space
for snow chains. To avoid damage to the vehi- cle or tires, observe the "Wheel and tire com-
binations" section under "Tires and wheels".
!Vehicles with steel wheels: if you mount
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps from the relevant wheels before mounting the
snow chains.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specially approved for your vehicle by
Mercedes-Benz, or are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
If you intend to mount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations (
Ypage 303).
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
iYou may wish to deactivate ESP®when pull-
ing away with snow chains installed
(
Ypage 191). You can thereby allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).
For more information on driving with the emer-
gency spare wheel, see (
Ypage 304).
Tire pressure
Tire pressure specifications
Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning a long journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi-
cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Operation with an emergency spare wheel:
information on operation with an emergency
spare wheel can be found in the general notes in
the "Emergency spare wheel" section
(
Ypage 304).
Further information on tire pressures can be
obtained at a qualified specialist workshop.
284Tire pressure
Wheels and tires

Tire and Loading Information placard
:Recommended tire pressures
The Tire and Loading Information placard is on
the B-pillar on the driver's side (
Ypage 290).
The Tire and Loading Information placard con-
tains the recommended tire pressures for cold
tires. The recommended tire pressures are valid
for the maximum permissible load and up to the
maximum permissible vehicle speed.
Tire pressure table
The tire pressure table is on the inside of the fuel
filler flap. It shows the tire pressure for all tires
permitted at the factory for this vehicle; see
illustration (example).
The tire pressure table contains the recommen-
ded pressures for cold tires for various operat-
ing conditions, i.e. differing load and speed con-
ditions.
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid for that tire size; see illustration (example).
The load conditions "partially laden" and "fully
laden" are defined in the table for different num-
bers of occupants and amounts of luggage. The
actual number of seats may differ.
Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g. R18.
Rim diameter is part of the tire size and can be
found on the tire sidewall (
Ypage 294).
If the tire pressures have been set to the lower
values for lighter loads and/or lower road
speeds, the pressures should be reset to the
higher values:
Rif you want to drive with an increased load
and/or
Rif you want to drive at higher road speeds
The tire pressures for increased loads and/or
higher road speeds, shown in the tire pressure
table, may have a negative effect on driving
comfort.
If the tire pressure is not set correctly, this can
lead to an excessive build up of heat and a sud-
den loss of pressure.
For more information, contact a qualified spe-
cialist workshop.
