Amerityre Makes Polyurethane Tire

Amerityre Corporation, Boulder City, Nevada, has developed a
revolutionary new tire design that uses polyurethane instead of rubber.
The company says that polyurethane tires are safer, less expensive to
manufacture and 100 percent recyclable.

During the testing phase, polyurethane car tires ran 51 degrees F
cooler than rubber ones in high-speed tests. The urethane tires also had
43 percent lower rolling resistance for greater fuel efficiency.

While rubber tires are made in layers and can separate, urethane
is “monolithic,” which means it is all one piece and won’t come apart.
