Twheel... future of wheels/tires

Just don't know if I could get use to seeing this on my car.
Comments???
The wheel(twheel) is a metal wheel with flexable outsection attached. The tire itself is only the tread section. The idea is that the tread section would be the only thing that gets replace.
You would never have a flat; unlike run-flats the tire doesn't use air. And since the only thing being replaced is the tread, there would be considerable less waste
Altough the idea might seem like a good one, I think the real problem they will have here is in public acceptance becasue it still looks like crap!!!!

As for expense, it would be very expenseive to start with, but if it ever became a mainstay products, it might not be. After all the only part you would be replaceing is the tread!!!!
I still think the worst problem is it look like crap!!!







. They cant be good for handling. It looks like they are very skinny.
