Hate to break it to you, but I believe that 4" wheels have driven just fine. IIRC, some teams using West Coast Drive did that a few years ago on a flat field. 1625 this last year went even smaller, at least in prototype form (or was that tiny tiny swerve module two years ago's offseason prototype?)

Curling was the 2009 game--required 6" wheels, slick floor, simulating 1/6 gravity--but the floor was nice and slick.

The real challenge: No wheels and no tank tracks. Legs or nothing!
