The Future of Tires? (introducing... the tweel)

[TGriffith]

Michelin has come up with a new invention which combines the tire and wheel together, to give you a tweel.  This tire is simply the tread adhered to the "rim" so that the tire does not need to be inflated, and never goes flat.  The design supposedly takes care of previous design problems with heat transfer.  The thing is ugly as heck - but it appears to have a ton of potential.

I've read about those before.  Guess you can't get em with whitewall. 
What do you think will happen if you try driving them through snow??
