Is this question posed at t=0, or at some positive time? Living near the beach, and having plowed through some sand on a bike (mountain tires) on one or two occasions, that does (kind of) change the answer. (Note: I usually stayed on the bike path. Did hit a few drifts, though, in addition to the time I took a shortcut off of it.)
If it's at some positive t, I'm going to be going with the skinny tires having more rolling resistance and more traction. But...
