Changing A Wheel - Mercedes-Benz G-Class Owner's Manual

typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size wheels,
you can interchange the wheels every 5,000
to 10,000 km, depending on the degree of
tyre wear. Ensure the direction of rotation is
maintained.
Clean the contact surfaces of the wheel and
the brake disc or brake drum thoroughly
every time a wheel is interchanged. Check the
tyre pressures.
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
G
WARNING
The water jet of circular-jet nozzles (dirt grind-
ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam-
aged tyres or chassis components replaced
immediately.

Changing a wheel

Fitting a wheel
Preparing the vehicle
X
Prepare the vehicle as described
( Y page 159).
X
If a trailer is coupled to the vehicle, uncou-
ple it.
X
Remove the vehicle tool kit and the jack
( Y page 155).
X
Secure the vehicle to prevent it from rolling
away.
X
Remove the spare tyre from the spare
wheel bracket at the rear (
from the spare wheel bracket underneath
the vehicle ( Y page 158).
Securing the vehicle against rolling
away
If your vehicle is equipped with wheel chocks,
these can be found behind the folding seat or
on the vehicle's chassis (chassis cab 6x6 with
crewcab) ( Y page 156).
The wheel chocks are an additional measure
for securing the vehicle from rolling away, e.g.
when changing a wheel.
X
On level ground: place chocks or other
suitable items under the 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.
