correct:
R designation
R model
When replacing tires, make sure to use the
correct:
R designation
R manufacturer
R model G
Warning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
Contact an authorized Mercedes-Benz Center if you require information on tested and rec- ommended wheels and tires for summer and
winter driving. Advice on purchasing and car-
ing for tires is also available there.
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and ask about:
R suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
in the "Wheel/tire combinations" section
(Y page 331).
Information on air pressure for the tires on
your vehicle can be found:
R on the tire pressure label on the fuel filler
flap
R in the "Tire pressure" section
i Further information on wheels and tires
can be obtained at any qualified specialist
workshop. Operation
Notes on driving
If the vehicle is heavily loaded, check the tire pressures and correct them if necessary.
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Oth-
erwise, the tires, particularly the sidewalls,
may be damaged. 306
OperationWheels and tires

Regular checking of wheels and tires
G
WARNING
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.
R Regularly check the wheels and tires of
your vehicle for damage at least once a
month, as well as after driving off-road or
on rough roads. Damage includes bulges
and deformation on tires, cuts, punctures,
cracks or severe corrosion on wheels, for
example. Damaged wheels can cause a
loss of tire pressure.
R Regularly check the tire tread depth and
the condition of the tread across the whole
width of the tire (Y page 307). In order to
inspect the inner side of the tire surface,
turn the steering wheel to full lock.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do notinstall anything onto the valve other than
the standard valve cap or a valve cap
approved by Mercedes-Benz for your vehi-
cle.
Do not install anything onto the valve, such as tire pressure monitoring systems.
R You should regularly check the pressure of
all your tires including the spare wheel, par- ticularly prior to long trips. Adjust the tire
pressure as necessary (Y page 314).
The service life of tires depends, among other things, on the following factors:
R Driving style
R Tire pressure
R Distance covered Tire tread
G
WARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of 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
width of all tires.
Minimum tire tread depth for:
R Summer tires: âin (3 mm)
R M+S tires: ãin (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached. Marking
:shows the tread wear indicator
(TWI). The arrow indicates the placement of
the tire tread.
Do not drive with tires which have too little
tread depth. tire traction on wet road surfaces decreases significantly when the tread depth
is less than 1
/ 8 in (3 mm).
Treadwear indicators (TWI) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth is
approximately 1
/ 16 in (1.6 mm). If this is the
case, the tire is so worn that it must be
replaced.
The recommended tread depth for summer
tires is at least 1
/ 8 in (3 mm). The recommen-
ded tread depth for winter tires is at least 1
/ 6
in (4 mm). Operation
307Wheels and tires Z

Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only mount approved tires of the correct
size onto the wheels.
R Tires are supplied with a protective layer
from the factory. Break in new tires at mod-
erate speeds for the first 60 miles
(100 km). They only reach their full per-
formance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear. This also applies to the spare wheel. Winter operation
General notes
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 327). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and braking power. Change the tires on your vehi-cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
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. G
WARNING
Wheel and tire dimensions as well as the type of tire can vary between the spare wheel and
the wheel to be replaced. When the spare
wheel is mounted, driving characteristics may be severely affected. There is a risk of an acci-
dent.
In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from the
wheel to be replaced for a short time.
R do not deactivate ESP ®
.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type.
Do not exceed a maximum speed of 50 mph
(80 km/h) if a spare wheel of a different size is installed.
At temperatures below 45 ‡ (+7 †), use all-
season tires or winter tires. Both types of tire
are identified by the M+S marking.
Not all tires with the M+S marking provide the
driving characteristics of winter tires. In addi-
tion to the M+S marking, winter tires also
have the isnowflake symbol on the tire
wall. Tires with this marking fulfill the require-
ments of the Rubber Manufacturers Associa-
tion (RMA) and the Rubber Association of
Canada (RAC) regarding snow traction, and
were specially developed for driving on snow.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter, since these tires have been
designed specifically for driving on snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac-
teristics. 308
Winter operationWheels and tires

Always observe the maximum permissible
speed specified for the M+S tire s you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressures (Y page 309).
X Restart the tire pressure monitor
(Y page 315).
i You can obtain information about winter
tires that have been approved by
Mercedes-Benz especially for your vehicle
at any Mercedes-Benz Service center.
i For further information about tires, see
(Y page 333). Snow chains
! Information about the use of snow chain
compatible AMG winter tires is applicable
for AMG tires. Use of snow chains is only
permissible with these tires.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
! If snow chains are mounted on the front
wheels, the snow chains could grind
against the bodywork or components of the chassis. This could result in damage to the
vehicle or the tires.
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.
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi- ble when you come to a road that is not
snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
If you intend to mount snow chains, please
bear the following points in mind:
R Snow chains cannot be mounted on all
wheel/tire combinations (Y page 331).
R Mount snow chains only in pairs and only
on the rear wheels. Observe the manufac-
turer's mounting instructions.
i You can deactivate ESP ®
(Y page 63)
when pulling away with snow chains instal-
led. You can thereby allow the wheels to
spin in a controlled manner, achieving an
increased driving force (cutting action). Tire pressure

Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the 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:
R monthly, at least
R if the load changes Tire pressure

If necessary, correct the tire pressure.
i The specifications on the sample Tire and
Loading Information placard and tire pres-
sure tables are examples. Tire pressure
specifications are vehicle-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 pres-
sure 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 a trailer: the applicable
value for the rear tires is the maximum tire
pressure value stated in the table inside the
fuel filler flap.
Further information on tire pressures can be
obtained at a qualified specialist workshop.
Tire and Loading Information placard :
Recommended tire pressures
The Tire and Loading Information placard is
on the B-pillar on the driver's side
(Y page 316).
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 Example: tire pressure table for all tires permitted
for this vehicle by the factory
The tire pressure table is on the inside of the fuel filler flap.
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
If a tire size precedes a tire pressure, the tire
pressure information following is only valid
for that tire size. The load conditions "partially laden" and "fully laden" are defined in the
table for different numbers of occupants and
amounts of luggage. The actual number of
seats may differ.
Some tire pressure tables only show the rim
diameter instead of the complete tire size,
e.g. R16. Rim diameter is part of the tire size
and can be found on the tire sidewall
(Y page 321).
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:
R if you want to drive with an increased load
and/or
R if you want to drive at higher road speeds
