2012 MERCEDES-BENZ G-CLASS SUV wheel size

Tyre pressure table
If a tyre size precedes a tyre pressure, the tyre
pressure informatio
nfollowing is only valid
for that tyre size. Instead of the complete tyre size, the rim
diameter alone, for example
R16, may be lis-
ted. Rim diameter
:is part of the tyre size and
can be found on the tyre sidewall.
Use a suitable pressure gauge to check the
tyre pressure. The outer appearance of a tyre
does not permit any reliable conclusion about
the tyre pressure.
On vehicles fitted with the electronic tyre
pressure monitor, the tyre pressure can be
checked using the on-board computer.
If possible, only correc ttyre pressures when
the tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direc tsunlight for at least three
hours and
R if the vehicle has no tbeen driven further
than 1.6 km
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure change by approximately 10 kPa
(0.1 bar/1.5 psi) per 10 †. Take this into
accoun twhen checking the pressure of warm
tyres. Only correct the tyre pressure if it is too
low for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics and thus the driving safety (e.g.
aquaplaning) 326

After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.

(Y page 309) contains information and notes
on how to deal with a fla ttyre. Interchanging the wheels
G
WARNING
Interchange the front and rear wheels only if
they have the same dimensions, fo rexample
size, offset, etc.
Have the tightening torque checked at a quali-
fied specialist workshop afte rawheel is
changed.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Ben zrecom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Always pay attention to the instructions and
safety notices in the section on "Wheel
changing and spare wheel fitting"
(Y page 330).
The wear patterns on the fron tand rea rtyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre. Changing

329Wheels and tyres Z

On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Maintain the direc-
tion of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and
reactivate the tyre pressure monitor
(Y page 327) if necessary. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit the spare wheel against the direc-
tion of rotation. Observe the time restriction
on use as well as the speed limitation speci-
fied on the spare wheel. Storing wheels
Store tyres that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel. Cleaning the wheels

WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent. Fitting

Preparing the vehicle X
Prepare the vehicle as described
(Y page 309).
X If a trailer is coupled to the vehicle, uncou-
ple it.
X Remove the vehicle tool kit and the jack
(Y page 306).
X Secure the vehicle to prevent it from rolling
away.
X Remove the spare wheel from the spare
wheel bracket (Y page 307).
Securing the vehicle against rolling
away X
On level ground: place chocks or other
suitable items unde rthe front and rear of
the wheel that is diagonally opposite the
wheel you wish to change.
X On downhill gradients: place chocks or
other suitable items in front of the wheels
of the front and rear axle.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
The following must be observed when raising
the vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel 330

General notes
! For safety reasons, Mercedes-Benzr ec-
ommends that you only use tyres, wheels
and accessories which have been approved
by Mercedes-Benzs pecifically for your
vehicle. These tyres have been specially
adapted for use with the driving safety sys-
tems, such as ABS or ESP ®
.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz .Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damage resulting from the use of tyres,
wheels or accessories othe rthan those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
i You will find a table of tyre pressures on
the inside of your vehicle's fuel filler flap. For further information on tyre pressure,
see (Y
page 325). Check tyre pressures
regularly and only when the tyres are cold.
i Notes on the vehicle equipment –always
fit the vehicle:
R with tyres of the same size on a given axle
(left/right)
R fit the same type of tyres on your vehicle
at a given time (summer tyres, winter
tyres, all-weather tyres, All Terrain tyres)
