Wheel rims and tyres
Checking rims
Make sure the ground is level
and firm and place the Maxi-
Scooter on its stand.
Visually inspect the rims for
defects.
Have any damaged rims in-
spected by a specialist work-
shop and replaced if neces-
sary, preferably by an author-
ised BMW Motorrad dealer.
Checking tyre tread depth
WARNING
Riding with badly worn tyres
Risk of accident due to impaired
handling
If applicable, have the tyres
changed in good time before
they wear to the minimum
tread depth permitted by law.
Make sure the ground is level
and firm and place the Maxi-
Scooter on its stand.
Measure the tyre tread depth
in the main tread grooves with
wear marks.
NOTICE
Wear indicators are built into the
main profile grooves on each
tyre. The tyre is worn out when
the tyre tread has worn down
to the level of the marks. The
locations of the marks are indic-
ated on the edge of the tyre, e.g.
by the letters TI, TWI or by an
arrow.
If the tyre tread is worn to min-
imum:
Replace tyre or tyres, as applic-
able.
Wheels
Effect of wheel size on
ABS
Wheel size is very important as a
parameter for the ABS. In partic-
ular, the diameter and the width
of the vehicle's wheels are pro-
grammed into the control unit
and are fundamental to all cal-
culations. Any change in these
influencing variables, caused for
example by a switch to wheels
other than those installed ex-
works, can have serious effects
