Measure tire tread depth in
main tread grooves with wear
indicators.
NOTICE
Tread wear marks are integrated
into the main grooves on every
tire. If the tire tread has worn
down to the level of the marks,
the tire is completely worn. The

is reached:

Tyre recommendation
For every size of tyre,
BMW Motorrad has tested and
approved certain makes as
roadworthy. BMW Motorrad
cannot evaluate the suitability of
other tyres, and can therefore
take no responsibility for their
driving safety.
BMW Motorrad recommends
only using the tyres tested and
approved by BMW Motorrad.

Affect of wheel size on
ABS
The wheel sizes play a major role
in the ABS system. The diam-
eter and width of the wheels
stored in the control unit have
particular significance as the ba-
sis for all necessary calculations.
A change in these sizes resulting
from conversion to wheels not
installed as standard equipment
can seriously affect the control
efficiency of the system.
The sensor rings required for
wheel speed detection must also
match the system installed and
must not be replaced.
If you want to equip your Maxi-
Scooter with different wheels,
please speak to a specialized
workshop, and preferably a
BMW Motorrad retailer. In some
cases the data stored in the
control unit can be adapted to
the new wheel sizes.
