BMW Motorrad K1300S - Manual (Page 92)

til a speed of approx. 20 mph
(30 km/h) is reached. Before ini-
tial reception of the tire inflation
pressure,
-- is shown in the dis-
play for each tire. The sensors
continue to transmit the mea-
sured values for approx. 15 min-
utes after the motorcycle comes
to a stop.
The control unit can manage four
sensors, and as a result two sets
of wheels with RDC sensors can
be driven. If a RDC control unit
is installed, however the wheels
have no sensors, then an error
message is output.
Tire inflation pressure
ranges
The RDC control unit distinguish-
es between three tire inflation
pressure ranges matched to the
motorcycle:
Inflation pressure within the
permissible tolerance.
Inflation pressure at the limits
of the permissible tolerance.
Inflation pressure outside the
permissible tolerance.
Temperature
compensation
The tire inflation pressures are
shown temperature-compensat-
ed in the multifunction display;
they refer to a tire air tempera-
ture of 68 °F (20 °C). As the air-
pressure testers at filling stations
show a temperature-dependent
tire inflation pressure, they do
not match the values indicated in
the multifunction display in most
cases.
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.
