This why tires are aired down for use in sand so they can “float” on the sand.
Hmm....I think you missed his point. He was referring to Pounds Per Square Inch of pressure on the ground, not in the tire. Meaning the skinnier the tire with the same GVWR will apply more pressure to that area as it is spread out over less area (Mass/Area). Just like the tires in the sand you refer to, we would lessen the air pressure so the tire was softer and the side walls would sag giving you a little more width in the soft sand. Now the side walls would be contacting the sand and since they were softer from the lower air pressure they would not spin quite as easily.
