Stuey;I first saw these advertised a couple of years ago. They called them "Tweels". I think the major tire companies are not too excited about the idea, but I see a few benefits like not being able to have a flat tire and alot less rubber going to the landfill. Do I like the way they look???? Not really. Maybe okay for a tuner, but not on a classic car. Just my 2 cents worth.
