Tweel

OK, I have long thought some sort of solid tire (tyre to the UKites) for cars would be a good solution to blowouts and wear problems, at least in some regards. Of course, the main problem with solid tires is the ride would be very stiff, causing discomfort for riders, and traction problems in certain conditions. I don't want to declare the problem solved, but Michelin seems to be moving towards a possible solution. The tire and wheel are combined, making a "tweel". This is a clever way of handling it, since the shock absorption is still integral to the "tire" part.
