Does anyone know if temperature changes will cause the inflation sensor to
alarm? I have only had the RX8 for three
weeks and was surprised when it went off on my way home from work. We had
about a 20 degree temperature drop
during the day. The alarm illuminated, stayed on for about 10 minutes of
drive time, then went off.
Any input appreciated.
Thanks,

Ideal gas law: PV=nRT

As Temperature (T) goes down and Volume, n & R remain constant, P (pressure)
must go down for the above equation to still be true.

.....that's about the extent of my recollection of Chemistry 101.....LOL!!!

Yup. A drop in temperature with no change in ambient pressure will cause
your tyres to deflate slightly.

Yup. When I took mine out for the initial test drive last Thursday the
indicator was lit up on the dash. As we drove on it finally went away as the
tires warmed up.

A very quick and dirty way of setting up the car for a track or autocross
event...
