    Tire pressure

    How much do you tinker with your tire pressure?

    Take this example. You leave someplace in the far north in the winter to fish Okeechobee. It is 10 below zero when you leave and it is 90 degrees in Florida. Since tire pressure changes about 1 psi for every 10 degree change in temperature you are looking at a 10 psi cold tire pressure change. Would you stop and adjust during the trip?


    Long haul truckers must deal with this often and I wonder what they do.

    Truckers—- we don’t do anything. I checked the psi in my steer tires religiously, 105 psi. ( with a gauge) drive tires and trailer tires I bumped them.

    I could always tell if the front tires were down as low as 95 psi, the back trailer (s) would start walking around. I have never towed my boat from one extreme to another. My FIL used to be a snowbird, leave the Midwest in Jan. ( pulling camper) And drive down to the Rio Valley for 4 months, he never messed with tire pressure

    I wold never mess with tire pressure mid-trip. Don't over-think it.

    If I went through a 100 degree shift then I guess I might consider checking, but for anything normal I never do. Sometimes in the spring and fall, the morning to afternoon temp swings can be 30 degrees but that is not worth worrying about.

    If my truck beeps at me and says a tire is low I fill it when I get home. If I remember.

    If I do that trip from ND to FL I would probably be starting out at 50-55 psi but by the time I get to fl they would be 65 so I. The range of endurance tires, I would check before the trip and somewhere that's 50*.
