AKRON (Aug. 30)—Goodyear has signed an exclusive agreement with Amerityre Corp. to jointly develop urethane tires with the ultimate objective of replacing rubber auto tires, according to an Aug. 30 news release. "Amerityre has developed what early tests show may be a viable compound for production of these tires," said Joe Gingo, Goodyear senior vice president for technology and global products planning. "If it can be done, we want to be the first to do it." Goodyear is interested in urethane tire development could offer ·significant product advantages" and efficient, cost-effective manufacturing processes requiring fewer capital costs than rubber tires, Gingo said. Richard Steinke, CEO of Boulder City, Nev.-based Amerityre, said his company chose to work with Goodyear on the project over other tire makers because of the Akron firm's "proven record of developing innovative products and processes," he said. Amerityre also sells flat-free urethane foam bicycle tires and has developed flat-fee tires for garden tractors and wheelbarrows.
