I have a TPMS system on my truck towing a 5th wheel.
I have found my pressures after 20 miles or so are within about 5 psi regardless of the ambient temperature during various trips.
The heat gain from the temperature rise from friction of the tire sidewalls is probably much greater than from ambient.
My cold temperature pressure is 80 psi and I see about 95psi after about 20 miles of towing where it usually stabilizes.
