2021 BMW M3 Owners Manual

The
pressure
increases
as
the
temperature
ofthe
tyre
increases,
for
example
while
driving
or
when
exposed
to
sunlight.
The
pressure
decreases
when
the
tyre
temperaj
ture
drops.
Due
to
the
system's
inherent
warning
thresholds,
therefore,
this
behaviour
may
cause
a
warning
to be
triggered
when
significant
temperature
drops
occur.
Sudden
loss
of
tyre
inflation
pressure
No
warning
can
be
given
in
the
event
of
extreme,sudden
tyre
failure
caused
by
external
factors.

Runflat
indicator
RPA
Principle
The
system
identifies
a
loss
of
tyre
inflation
presj
sure
by
comparing
the
rotational
speeds
of
the
individual
wheels
during
the
journey.
If
a
tyre
loses
inflation
pressure,
its
diameter
changes.
This
in
turn
alters
the
rotational
speed of
the
corresponding
wheel.
The
discrepancy
willbe
detected
and
reported
as
a
flat
tyre.
The
system
does
not
measure
the
tyre
inflation
pressure
as
such.

during
a
wheel
change.
Even
if
the
safety
measures
are
complied
with,
there
is
a
risk
of the
