You didn't even wait for the really stupid answers!
Not all sand is the same (as some have alluded to above). If it has an even distribution of particles (usually the result of glacial action) it will pack well. Littoral (Beach) and river sand is typically more sorted and does not pack well, though moisture allows it to pack a little due to capillary action, too much can result in quicksand. Tires with less pressure actually roll easier in loose materials, so your mileage will improve (from 14 to 15 mpg).
Moral: Have a seive analysis on the sand to tell exactly the nature of the sand and fill the tires accordingly.
Really this "info" is necessary only for non-Hummers, Hummers can go through anything!
