Regular wheel and tire checks
GWARNING
Damaged tire scan cause tire inflation pres-
sure loss. As aresult, yo ucould lose control of
your vehicle. There is ariskofa ccident.
Check the tire sregularl yfor signs of damage
and replace any damaged tire simmediately.
Check the wheel sand tire sofyourv ehicl efor
damag eregularly, i.e .atleast every two weeks,
as well as afte rdriving off-road or on rough
roads. Damaged wheel scan cause alos soft ire
pressure. Payp articula rattention to damage
such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosio nonwheels
Regularly check the tire trea ddepth and the
condition of the trea dacross the wholew idth of
the tire (
Ypage 268). If necessary, turn the
front wheel stofullloc kino rder to inspect the
inner sid eofthe tire surface.
All wheel smusth aveav alve cap to protect the
valve against dirt and moisture. Do not install
anything onto the valve othe rthan the standard
valve cap or othe rvalve cap sapproved for your
vehicl ebyd ealers listed on the inside of the
front cover. Do not install any othe rvalve caps
or systems ,e.g. tire pressure monitor systems.
Regularly check the pressure of al lthe tires,
particularly prior to long trips. Adjust the tire
pressure if neces sary (
Ypage 270).
The service life of tire sdepends on various fac-
tors, including the following:
Rdriving style
Rtire pressure
Rmileage
Tire tread
GWARNING
Insufficient tire trea dwillr educe tire traction.
The tire is no longer able to dissipate water.
Thi sm eans that on we troa ds urfaces, the risk
of hydroplaning increases, in particula rwhere
speed is not adapted to suit the driving con-
ditions .There is ariskofa ccident.
If the tire pressure is too hig hortoo low, tires
may exhibi tdifferent level sofwearatd iffer-
ent locations on the tire tread. Thus, you
shoul dregularl ycheck the trea ddepth and
the condition of the trea dacross the entire

Minimum tire trea ddepth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons,r eplace the tiresbefore

282What yous hould knowabout wheels an dtires
Wheel sand tires
GVW (Gross VehicleWeight)
The gross vehicle weight includes the weight of
the vehicle including fuel ,tools, spare wheel,
accessories installed, occupants, luggage and
the drawbar noseweight if applicable. The gross
vehicle weight must never exceed the permissi-
ble gross weight (GVWR) specified on the
B-pilla ronthe driver's side (
Ypage 294).
GVWR (Gross Vehicl eWeight Rating)
The GVWR is the maximu mpermitted gross
weight of the full yladen vehicle (weight of the
vehicle including all accessories, occupants,
fuel ,luggage and the drawbar noseweight if
applicable).T he permissibleg ross weight is
specified on the vehicle identification plate on
the B-pilla ronthe driver's side (
Ypage 294).
Maximum weight of the laden vehicle
The maximu mweight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe loadl imit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa are the
equivalent of 1psi.A nother tire pressure unit is
bar. 100 kilopascals (kPa) are the equivalent of
1b ar.
Load index
In addition to the loadb earing index,aload
index can be stamped onto the sidewal lofthe
tire. It specifies the load-bearing capacity of the
tire more precisely.
Curb weight
The weight of avehicle with standard equipment
including the maximu mfilling capacity of fuel,
oil, and coolant. It also includes the air-condi-
tioning system and optional equipment if these
are installed on the vehicle ,but does not include
passengers or luggage.
Maximum tire load
The maximu mtire loadink ilograms or pounds is
the maximu mweight for which atire is
approved.
Maximum permissiblet ire pressure
Maximumpermissiblet ire pressure for one tire.
Maximum load on one tire
Maximumloadono ne tire. This is calculated by
dividing
the maximu maxle loadofo ne axle by
two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pressure.
Aspec tratio
Relationshi pbetwee ntire heighta nd width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's surface.
Tire pressure is specified in pounds per square
inch (psi), in kilopascal (kPa) or in bar. Tire pres-
sure shoul donly be corrected when the tires are
cold.
Col dtire pressure
The tires are cold:
Rif the vehicle has been parked for at least
three hours withou tdirect sunlight on the
tires, and
Rif the vehicle has not been driven further than
1m ile (1.6 km)
Tire tread
The part of the tire that comes into contact with
the road.
Tire bead
The tire beade nsures that the tire sits securely
on the wheel. There are severals teel wiresinthe
beadtop revent the tire from coming loose from
the whee lrim.
Sidewall
The part of the tire betwee nthe tread and the
tire 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, aroof rack or ahigh-performance bat-
tery, are not included in the curb weight and the weight of the accessories.

When usingawheel/spare wheel with anew or

General notes
!
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.
!For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and
accessories which have been specially
approved by Mercedes-Benz for your vehicle.
These tires have been specially adapted for
use with the driving safety systems, such as
ABS or ESP
®.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz .Certain
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 acceptsnol iability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Further information on wheels, tires and
approved combinations can be obtained from
any qualified specialist workshop.
!Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and the
risk of damage to the wheels and tires as a
result of driving over obstacles increases.
You will find atable with the recommended tire
pressures for various vehicle loads on the inside
of your vehicle's fuel filler flap or under "Tire
pressure tables" (
Ypage 278). You can find fur- ther information under "Tire pressure"
(
Ypage 270).
Check tire pressures regularly and only when
the tires are cold.
