and after the tires have heated up?

pressures will increase a few pounds with heat/friction... so as a baseline set them cold to specs

Tire pressure should be checked when the tires are cold. Air expands once heated & pressures can vary.

you don't always check your pressures cold
air expands as it is heated and will give you a bad reading

cuz no tier is completly air tight and if you have bad air pressure it could rob you of gas milage and could end up being a big hazard
