Tire Inflation Pressure - BMW R 1200 RT Manual

the measured values for approx.
6
15 minutes after the motorcycle
comes to a stop.

The control unit can manage four
sensors, and as a result two sets
of wheels with TPC/RDC sen-
sors can be driven. If a TPC/RDC
control unit is installed, however
the wheels have no sensors, then
an error message is output.

Tire inflation pressure

ranges
The TPC/RDC control unit distin-
guishes between three inflation
pressure ranges matched to the
motorcycle:
z
Inflation pressure within the
permissible tolerance.
Inflation pressure at the limits
of the permissible tolerance.
Inflation pressure outside the
permissible tolerance.
A warning is also output if the
tire inflation pressure drops rapid-
ly within the permissible toler-
ance.
Temperature
compensation
The tire inflation pressure is tem-
perature dependent, i.e. it in-
creases or decreases together
with the tire temperature. The
tire temperature is dependent on
the ambient temperature and on
the driving style and duration.
The tire inflation pressures are
shown temperature-compensat-
ed in the multifunction display;
they refer to a tire temperature
of 68 °F (20 °C). No tempera-
ture compensation takes place in
the air pressure testers at filling
stations, i.e. the measured tire in-
flation pressure is dependent on
the tire temperature. As a result,
the values displayed there do not
match the values shown in the
multifunction display in most cas-
es.
Adjusting inflation
pressure
Compare the TPC/RDC value in
the multifunction display with the
value on the back cover of the
Rider's Manual. The difference
between the two values must be
compensated with the air pres-
sure tester at the filling station.
Example: According to the
Rider's Manual, the tire inflation
pressure is to be 36.3 psi
(2.5 bar), however 33.4 psi
(2.3 bar) is shown in the
multifunction display, i.e. it is low
by 2.9 psi (0.2 bar). The tester at
the filling station indicates 34.8
psi (2.4 bar). This value must be
increased by 2.9 psi (0.2 bar) to
37.7 psi (2.6 bar) to produce the
correct tire inflation pressure.
