Its DuraSeal technology features a “built-in sealant” that allows truck drivers to continue operating after a tyre is punctured. The technology allows the tyre to remain in service until it is re-treaded.
Good year claims its tests showed that tyres with the new technology last up to six times longer than conventional medium truck tyres before removal for repair.
The new technology uses a gel-like, solvent-free compound built into the inner liner of the tyre. 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 tyre casing maintains its sealing capability after it is re-treaded.
DuraSeal technology is being launched in a range of mixed-service tyres, where tyre punctures are a daily hazard. Goodyear expects the to be popular in logging, landfill, construction, road building and other severe service applications.
