I know on the 570s the front tires are suppose to be 29 and rear at 32. In the cold mornings the tour pressure drops and then goes up as temperature rises during drive. How should I be measuring tie pressure and what is too high? Here’sa snap shot after about 30 min of driving.

In the cold weather I usually put the tires 2psi higher when cold. That means when they heat up they will go higher, as you’re noticing. With normal driving it’s perfectly fine. If you are tracking or going out for a nice spirited run, I’d recommend taking a couple lbs out after heated up.

pV = nRT

PV = nRT = NkT

I'll simplify for the less nerdy. For every 10 degrees F you'll see 1 PSI of pressure change, approximately.
