Inter changing the front and rear wheels can
se verely impair the driving characteristics.
The disk brakes or wheel suspension compo‐

On vehicles with the same front and rear wheel
size, you can inter change the wheels every 5,000
to 10,000 km depending on thewe ar. Ensure the

When using a spare wheel (which is dif fere nt
from the wheel tobe replaced) a top speed of
80 km/h must not be exceeded.
R The tyre pressure of the spare wheel must be
ch ecked before starting a journey
(/ page 251).
