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 motor-
cycle 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
Tyre recommendation
For each size of tyre,
BMW Motorrad tests and
classifies as roadworthy certain
makes. BMW Motorrad cannot
assess the suitability or provide
any guarantee of road safety for
other tyres.
BMW Motorrad recommends
using only tyres tested by
BMW Motorrad.

Effect of wheel size on
chassis and suspension
control systems
Wheel size is very important
as a parameter for the frame
and suspension control systems
ABS and DTC. In particular, the
diameter and the width of the
vehicle's wheels are programmed
into the control unit and are fun-
damental to all calculations. Any
change in these influencing vari-
ables, caused for example by
a switch to wheels other than
those installed ex-works, can
have serious effects on the per-
formance of the control systems.
The sensor rings are essential
for correct wheel speed detec-
tion; they too must match the
motorcycle's control systems and
consequently cannot be replaced.
