Wheels - BMW C 650 GT Rider's Manual

Make sure the ground is level
and firm and place the Scooter
on its stand.
Measure the tyre tread depth
in the main tread grooves with
wear marks.
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 indicated 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.

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.
You can obtain detailed informa-
tion from your authorised BMW
Motorrad dealer or on the Inter-
net at www.bmw-motorrad.com.
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 a 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
on the performance of the sys-
tem.
The sensor rings are essential
for correct road-speed calcula-
tion, and they too must match
the vehicle's system and con-
sequently cannot be changed.
If you decide that you would
like to fit non-standard wheels
to your Scooter, it is very im-
portant to consult a specialist
workshop beforehand, preferably
an authorised BMW Motorrad
dealer. In some cases, the data
programmed into the control unit
can be changed to suit the new
wheel sizes.
