Mercedes-Benz GLS Owner's Manual page 416

Only interchange the front and rear
#
wheels if the wheels and tyres have the
same dimensions.
Interchanging the front and rear wheels if the
wheels or tyres have different dimensions can
render the general operating permit invalid.
The wear patterns on the front and rear wheels
differ:
front wheels wear more on the tyre shoulder
R
rear wheels wear more in the centre of the
R
tyre
Do not drive with tyres that have too little tread
depth. This significantly reduces traction on wet
roads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can interchange the wheels every
5000 to 10,000 km, depending on the wear.
Ensure the direction of rotation is maintained for
the wheels.
Observe the instructions and safety notes on
"Changing a wheel" when doing so
( page 414).

Notes on storing wheels

R
dry and preferably dark place.
Protect the tyres from contact with oil,
R
grease or fuel.
