OK, thanks all for your answers. 3 yes, 3 no & 1 I'm not sure.
I always check the pressure before moving, as it is flashing on the dashboard.
I was just wondering how many folks reduce the air pressure, ie let air out because of the rise in ambient air temp.
Last year when I left, I had 80psi @ 30 degrees, the second morning when leaving Tampa the temp was 65 degrees the TST said 2 tires @ 83psi & 2 tires @ 84psi. I did not let air out and based on the 3 no's, probably won't do it this year. If I have a blow out, you yes's can holler out the window as you drive by & say "I told you to adjust it"...........
