Rims And Tyres - BMW Motorrad R 1250 GS 2002 Rider's Manual

188 MAINTENANCE
WARNING
Tendency of valve inserts
installed vertically to open
by themselves at high riding
speeds
Sudden loss of tyre pressure
Install valve caps fitted with
rubber sealing rings and
tighten firmly.
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Check tyre pressures against
the data below.
Tyre pressure, front
2.5 bar (sport riding)
2.5 bar (One-up, tyre cold)
2.5 bar (Two-up mode with
load, with cold tyres)
Tyre pressure, rear
2.9 bar (One-up, tyre cold)
2.9 bar (Two-up mode with
load, with cold tyres)
If tyre pressure is too low:
Correct tyre pressure.
Tyre pressures can be de-
termined with tyre pres-
sure control (RDC). The tyre-
pressure readings shown in the
instrument cluster are tempe-
rature-compensated and are
always referenced to a tyre
air temperature of 20 °C. The
gauges on forecourt air lines
do not compensate for tem-
perature. Consequently, the
values they show do not usually
tally with the pressure readings
shown by the TFT display.

RIMS AND TYRES

Place the motorcycle on its
stand on firm, even ground.
Visually inspect the rims for
defects.
Have damaged rims inspec-
ted by a specialist workshop
and replaced if necessary,
preferably by an authorised
BMW Motorrad dealer.
Checking tyre tread depth
WARNING
Riding with badly worn tyres
Risk of accident due to im-
paired handling
If applicable, have the tyres

fore they wear to the min-
imum tread depth permitted
by law.
Place the motorcycle on its
stand on firm, even ground.
