You can also use a tire pressure gauge. Check the pressure in the morning before driving as the tires heat up after driving and will give an inflated number.hey guys im kind of a noob so dont mind if i ask questions that are pretty simple to answer >< but how do i find out how many psi im running?
It's not exact like that everytime. Because I have to drive to fill my tires and they're warm, what I'll do is fill up to like 40 PSI, then drive home and in the morning I'll adjust the pressure then very carefully since I can't add air at that point.Does the tire pressure rise in all the tires more or less equally when driving? Say if I go to a pump station and inflate to say 38PSI, and then check the pressure once the air in the tires has cooled down, would all of them drop down equally to say 35 PSI?
