One more thing my Tire temperatures were running a few degrees above the outside temps. The tires were not hot at all, only problem is the 20 degree rise of the psi
Those two pieces of data don't match.
Have you actually felt the tires to see how hot they really ARE ?
HEAT is the only thing that will increase the pressure.
I think there is no validity to the temp readings of a TPMS.....since the sensor is not mounted on the tire itself. For tires your size, they often are at the end of a VERY long metal valve stem.
I don't pay much attention to the actual readings on my TPMS as they aren't very accurate but seems like I remember increases similar to that in the summer time. I have "off brand" truck tires.
