It is only permissible to fit a different wheel
size in the event of a flat tyre in order to
drive to the specialist workshop.
R
Only fit tyres of the correct size onto the
wheels.
R
Do not make any modifications to the brake
system, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may invalidate the vehicle's
general operating permit.
R
Vehicles with a tyre pressure monitoring
system: all fitted wheels must be equipped
with functioning sensors for the tyre pres‐
sure monitoring system.
R
At temperatures below 7°C use winter tyres
or all-season tyres marked M+S for all
wheels.
Winter tyres bearing the
i snowflake
symbol in addition to the M+S marking pro‐
vide the best possible grip in wintry road
conditions.
R
For M+S tyres, only use tyres with the same
tread.
R
Observe the maximum permissible speed for
the M+S tyres fitted.
If this is below the vehicle's maximum speed,
this must be indicated by an appropriate
label in the driver's field of vision.
R
Run in new tyres at moderate speeds for the
first 100 km.
R
Replace the tyres after six years at the latest,
regardless of wear.

Notes on interchanging wheels
& WARNING Risk of injury through differ‐
ent wheel sizes
Interchanging the front and rear wheels can
severely impair the driving characteristics.
The disk brakes or wheel suspension compo‐
nents may also be damaged.
#
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:
R
front wheels wear more on the tyre shoulder
R
rear wheels wear more in the centre of the
tyre
Do not drive with tyres that have too little tread
depth. This significantly reduces traction on wet
roads (aquaplaning).
