Where can we find good pneumatic wheels?

And that made the wheelbase shorter than ours in 2006, where we had very little drop and 6 wheels. Long wheelbase=tougher turning, in general. This is why most 6WD robots have a dropped center wheel or omnis (or other low-friction wheels) on the corners. We didn't have nearly as much trouble after putting Skyways on the front corners.

Link to the McMaster wheels: go to the McMaster site and enter the part number into the search box. You'll get the page; the wheels are near the bottom. We used the gray treaded ones.
