Smaller gaps trap the mud in between the tire lugs, which turns the tire into something resembling a "slick" with no tread at all, which will have no traction in mud. A paddle tire is an even more extreme version of this, optimized for mud or sand. The paddle provides superior traction in the sand, in part because the paddles dig into the sand ...
