Mercedes-Benz CLS Operator's Manual page 352

Interchanging the front and rear wheels if the
wheels or tyres have different dimensions can
render the general operating permit invalid.
Observe the instructions and safety notes on
"Changing a wheel" ( page 345)
/
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
5,000 to 10,000 km, depending on the wear.
Ensure the direction of rotation is maintained for
the wheels.
Notes on storing wheels
When storing wheels, observe the following notes:
After removing wheels, store them in a cool,
R
dry and preferably dark place.
Protect the tyres from contact with oil, grease
R
or fuel.
