Am getting a S-646. Would dearly love to get drive wheels/tires like the new tech Quantum pneumatic run flats. (Those can't be mounted on Quickies.) (Described here by Mark Smith : http://www.wheelchairjunkie.com/foru...true#Post64530 _ about half way down, #64513).

Anybody know if Quickie is coming out w/ something similar?

And, anybody know where or who to write at Quickie w/ questions like that?
