I use one of the more expensive TPMS systems and here are the parameters for alerts for that system. To the best of my knowledge, I cannot change these parameters.
Pressure loss of 3 PSI or more in less than 2 minutes.
Pressure loss of 6 PSI or more in 2 to 10 minutes.
Pressure loss of 15% or more of the baseline pressure.
Pressure increase of 20% or more of the baseline pressure.
Internal tire temperature of 167°F (75°C).
