I'm not convinced of the utility of this wheel design.

Different wheel widths and diameters are certainly suited for different tasks, but in an area with no roads why not produce a simple wheel with large diameter and width suited for poor roads? There seems to be little value in allowing it to convert to a wheel design suited for better terrain.

Further, optimal wheel design matters most when you're propelling or steering the vehicle, as in a bicycle or motorized car / cart. In this case I suspect you'd be better off with the advantages of a pneumatic tire than the adaptability of this "Roadless" design. None of the Roadless concepts incorporate a pressurized air tire, arguably one of the most important transportation innovations in history.

And in any case, the added complexity seems unwelcome in this sort of environment.

Am I missing something?
