Notes on rotating wheels
& WARNING Risk of injury through differ‐
ent wheel sizes
Interchanging the front and rear wheels if the
wheels or tires have different dimensions
may severely impair the driving characteris‐
tics.
The wheel brakes or wheel suspension com‐
ponents may also be damaged.
#
Rotate front and rear wheels only if the
wheels and tires are of the same dimen‐
sions.
The wear patterns on the front and rear wheels
differ:
R
Front wheels wear more on the shoulder of
the tire
R
Rear wheels wear more at the center of the
tire
Do not drive with tires that have too little tread
depth. This significantly reduces traction on wet
roads (hydroplaning).
On vehicles that have the same size front and
rear wheels, rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
available, rotate the tires every
3,000 to 6,000 miles (5,000 to 10,000 km),
depending on the wear. Ensure that the direction
of rotation is maintained.
Observe the instructions and safety notes on
"Changing a wheel" when doing so
(

page 288).

notes:
R
After removing wheels, store them in a cool,
dry and preferably dark place.
R
Protect the tires from contact with oil, grease
or fuel.
