Those with tire pressure monitoring systems..
Those that have tire pressure monitor systems, if you air up to max, say 80psi or in my case 110psi. on a cold tire, On a trip how much of an increase can I expect in tire pressure after driving all d...

Probably you filled to 80 psi when outside 65 degr F and that hot day was about 90 degrees F. then the "cold"measured pressure would be already higher then 80 psi and say temp rising by riding that 47 degrees I wrote gives 137 degrees to wich probably that 95 psi belongs .
Filled it in in my spreadsheet and filled at 80 psi at 65 degrees gives 84.5psi at 90 degrees and 93 psi at 137 degrees F.
To 95 psi belongs 148 degrees.
so temperature measurement of TMPS is mostly inacurate, but you dont need that . You can calculate the temperature from the cold and warm pressure and the fill temperature outside.
TMPS could be chached in their software that they calculate it from start outside temp and those cold and warm pressure.
Probably more accurate then as its done now.
Pressure measurement of TMPS is mostly pretty accurate but also depends on the quality.
