A driver picks up a trailer from a drop yard. Before departing, the driver does a walk-around inspection, kicks the tires, checks the lights and then sticks it into the wind. He or she has no idea how much air pressure is in those tires, except to be fairly sure none of them is flat — visibly flat, that is. Any one or several of those tires could be underinflated, or even technically flat.
