Our team uses a six-wheel design, with the center wheels lowered slightly (1/8 to 1/4 inch). A bunch of teams in the Pacific Northwest use this basic design. We learned it from team 492.

The past two years, we've used high traction IFI wheels in the center and Skyway wheels at the corners. If you can keep your robot reasonably balanced over the center wheels, you get a powerful base that can turn in place, pushes well no matter how the weight is distributed and climbs ramps very well.
