Polyurethane Spare Tire Runs the Distance

Zero-Pressure Spare Tire Runs Great in Initial Testing

BOULDER CITY, Nev., Feb. 16 -- Amerityre Corporation (BULLETIN BOARD: AMTY) . Amerityre Corporation announced today that initial testing of its polyurethane elastomer compound in an endurance test for its zero-pressure spare tire showed great results. The test tire ran at 50 miles per hour with increasing loads for beyond the required 34 hours. The endurance test was conducted at an independent laboratory and is one of four laboratory tests required under FMVSS 129, the applicable safety standard for non-pneumatic car tires.

According to Richard A. Steinke, Amerityre's President and Chief Executive Officer, the test tire performed outstanding for the duration of the test. "We couldn't have been more pleased with the tire's performance. Our polyurethane compound performed beyond our expectations. In particular, we were impressed with the low temperature readings," Steinke said. "I believe our tire is the first to go the distance," he added.

The zero-pressure spare tire is under development by Amerityre in response to a growing concern among consumers and government agencies such as the National Highway Traffic Safety Administration (NHTSA) for post-crash fires caused by fuel leakage in high-impact rear collisions. A high-pressure pneumatic 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.

In addition to collision safety, Amerityre's objective is to offer equal or better performance to that of comparable rubber high-pressure spare tires. Although the tire is being developed for "temporary" use, Amerityre believes that a zero-pressure spare tire can be safely operated at 50 mph for over 2,000 miles. Consumers won'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. Loss in air pressure greatly affects the performance of a high-pressure spare tire. The zero-pressure spare tire, on the other hand, will give drivers an always ready solution in the event of a failed pneumatic tire.
