When it got in the upper 80's and low 90's they went up quite a bit. I like to keep the tires 2-3 lbs above recommended cold pressure.Which reinforces the reminder.
what temp and pressure caused you to reduce pressure?
As I'm sure you know, psi in tires change 1 psi for every 10* ambient air temp change and while driving the psi's can go up as much as 5 psi due to tire-road surface friction.When it got in the upper 80's and low 90's they went up quite a bit.

Yep. Mine were up in the low 40s when it got to 90 degrees last week and driving for a while. That's when I let some air out.As I'm sure you know, psi in tires change 1 psi for every 10* ambient air temp change and while driving the psi's can go up as much as 5 psi due to tire-road surface friction.
