Don't know if this is any help but worth keeping in mind. I notice that you're in Pa. You must be getting some cooler nights by now. The tires will loose some pressure as the temp drops. Maybe that's why the TMPS was nuts in the morning.
I'm in Virginia & it's been in the low 50's in the early AM. I'm running +2 PSI all around so I don't have to re-set the tires so often.
