Amerityre Begins Development of First-Ever Polyurethane Spare Tires

Zero-Pressure Spare Tires Offer More Safety and Reliability Than Traditional Spare Tires

BOULDER CITY, Nev., Dec. 8 -- Amerityre Corporation (BULLETIN BOARD: AMTY) announced today its development plans for a zero-pressure spare tire made from polyurethane elastomer. Prototype development has begun and performance testing on the spare tire, intended for passenger cars, light trucks and SUVs, will begin by early January 2005.

The product is under development in response to a growing concern among consumers and organizations such as The National Highway Traffic Safety Administration (NHTSA) for post-crash fires caused by fuel leakage in high-impact rear collisions. The high-pressure spare tire's close proximity, in most cases, to the fuel tank can be an explosion hazard for vehicles involved in high-impact rear collisions. A zero-pressure spare tire reduces the risk of causing an explosion.

With tougher NHTSA regulations on manufacturers of light-duty passenger vehicles coming in September 2006, Amerityre is positioning itself to help manufacturers and suppliers meet stricter safety regulations involving rear-end collisions.

"The benefits of polyurethane elastomer as a tire compound are endless," said Richard Steinke, president of Amerityre. "We are looking forward to completing testing and then introducing this product to manufacturers and suppliers to demonstrate its benefits, particularly its use as a safety device in passenger vehicles."

In addition to collision safety, zero-pressure spare tires offer equal or better performance to that of comparable rubber high-pressure spare tires. Amerityre believes that a zero-pressure spare made from polyurethane elastomer can be safely operated at 50 mph for over 2,000 miles. Consumers also don't need to worry about air pressure in polyurethane elastomer spare tires, unlike traditional high-pressure spare tires, which lose pressure through permeation over time. This loss in air pressure greatly affects the performance of a high-pressure spare tire. The polyurethane elastomer spare tire, on the other hand, offers drivers an always ready solution in the event of a failed tire.
