could have sworn I've seen this type of wheel somewhere before...

Big deal maker - no more tire blowouts
I think they need sidewalls though for high speed applications, can you imagine highway speeds with some mud caked into one of those? Can you say off-balance?
I saw that before on Daily Planet. It looks like a great idea.
What was that 4 wheeled bike/ATV thing that guy was riding? That looked like a lot of fun.
