Has anyone looked into this?

Wouldn't that be like using a can of "fix a flat" on a car? But with the wheel being semi-pneumatic the material should be able to help define the wheels compressibility (is that a word?) by helping the existing rigidity or the tire material and shape.

Sounds like a neat idea to try, but it would seem you are either going to have to cut a ring shaped donut to put inside the tire or use expanding foam.
