This.
The trucking industry does re-treading (those big circular pieces found in the middle of the highway).
The Tweel would be a good replacement for the tire if the spokes held up or were individually replaceable. Right now they are thin and exposed to the elements. There is a design problem in there which could be fixed by some engineer in the future.
