From my 4-wheeling experience I would like to comment that tires with large tread blocks are more likely to DIG than grip in sand, especially soft sand. My bald old street tires worked far better in sugar sand than the brand new Mud-Terrains, and my buddies with Boggers would get stuck first each time. If you're using golf cart/atv tires, go with a street or "all-terrain" tread for use in sand.
