My tire pressure actually looked like this when my car was delivered by Carvana.

    Are you at low elevation? If your car came from high elevation it would have added a few pounds of pressure by the time it got down to you. Not 60 extra lbs obviously haha

    That's the opposite of how that works.

    Tires are a gauge pressure, meaning pressure vs ambient pressure.

    14.7 psia (absolute) at sea level. And getting less as you go higher elevation.

    12.7psia ambient is ~4000ft elevation 10.7psia ambient is ~8500ft elevation

    So if it you start at sea level with 40psig in your tires, when you get to 8500ft elevation and measure the tires you'll be ~44psig.

    If you start at 8500ft at 40psig, when you get to sea level they'll be ~36psig.
