For most vehicles / tires, it's not worth getting out of the truck, much less having to air back up if you don't go down to at least 10 PSI.
To get a good ball park, park on pavement and measure from the ground to the bottom edge of the rim. Reducing this distance by 25% will give you the largest foot print you can get (unless you want to get technical and do a ton of measuring). It depends on the tire and weight of the vehicle, but in most cases your looking at about 5 PSI, but may be anywhere from 2 to 10 PSI.
