Wheel rims and tires

Check wheel rims
Make sure ground is level and
firm and place Maxi-Scooter on
its center stand.
Subject wheel rims to visual
inspection for defects.
Have damaged rims checked
and, if necessary, replaced
by a specialist service facil-
ity, preferably an authorized
BMW Motorrad retailer.
Checking tire tread depth
The handling of your Maxi-
Scooter can already change
for the worse before the legally
prescribed minimum tread depth
is reached.
Have tires replaced even be-
fore the minimum tread depth
is reached.
Make sure ground is level and
firm and place Maxi-Scooter on
its center stand.
Measure tire tread depth in
main tread grooves with wear
indicators.
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 locations
of the marks are indicated on
the edge of the tire, e.g. by the
letters TI, TWI or by an arrow.
When the minimum tread depth
is reached:
Replace the worn tires.

Tire recommendation
For every size of tire,
BMW Motorrad has tested and
approved certain makes as
roadworthy. BMW Motorrad
cannot evaluate the suitability of
other tires, and can therefore
take no responsibility for their
driving safety.
BMW Motorrad recommends
only using the tires tested and
approved by BMW Motorrad.
Extensive information is
available at your authorized
BMW Motorrad retailer or on
the Internet at www.bmw-
motorrad.com.
Affect of wheel size on
ABS
The wheel sizes play a major role
with the ABS system. The di-
ameter and width of the wheels
stored in the control unit have
particular significance as the
basis for all necessary calcula-
tions. A change in these sizes
due to conversion to others than
the wheels installed as standard
equipment can seriously affect
the control comfort of the sys-
tem.
