Goodyear Launches Self-Sealing Truck Tires

January 25, 2005

LAS VEGAS — The Goodyear Tire & Rubber Company announced on January 17 that it has developed a commercial tire technology that repairs tire punctures when they occur, greatly reducing vehicle downtime and service calls.Goodyear's new DuraSeal technology features a "built-in sealant" that allows truck drivers to continue operating after a tire is punctured. The technology allows the tire to remain in service until it is retreaded.Tires featuring DuraSeal technology last up to six times longer than conventional medium truck tires before removal for repair, according to Goodyear tests.The new technology uses a gel-like, solvent-free compound built into the inner liner of the tire. It is designed to consistently and instantly seal punctures up to 1/4-inch in the tread area.The technology is claimed to deliver superior sealing efficiency compared to aftermarket liquid sealants and the tire casing maintains its sealing capability after it is re-treaded.DuraSeal technology is being launched in a range of mixed-service tires, where tire punctures are a daily hazard. Goodyear expects the to be popular in logging, landfill, construction, road building and other severe service applications.
