Where The Urethane Meets The Road

Amerityre is trying to market flat-free closed-cell polyurethane foam tires as spares for cars. No air needed to pump them up, as the design is solid. They already market them for bicycles, golf carts, lawn mowers, and such. The advantages are that the tread can't separate from the carcass (ala the Ford Explorer), they don't explode (!) when hit in a rear-end collisions, and they can be used to travel 50 mph for over 2,000 miles verses the 50 miles with standard spares. Urethane tires have been tried in the past, but there have been problems with traction. Targeting the spare tire market seems like a brilliant way to get a foot in the door,
