The closer together the outer wheels are the more they have to be dragged sideways to turn. It will work, but how well it actually performs is dependant upon how close together the outer wheels actually are. I would say that all the robots above have wheels close enough together that performace wouldn't be affected much at all. If you were thinking along those lines then you should be good.

Further apart = less turning scrub = better
