Goodyear expands use of DuraSeal technology

Goodyear Tire & Rubber Co.'s DuraSeal self-sealing commercial tire technology now will be available in the company's Unisteel G177 severe-service drive tires.

The technology was previously only available in Goodyear Unisteel G287 MSA and G288 MSA mixed-service tires.

DuraSeal is a gel-like, solvent-free compound built into the inner liner of the tire which consistently and instantly seals punctures up to 1/4-inch in the tread area, greatly reducing vehicle downtime.

DuraSeal tires also can be retreaded and retain sealing effectiveness.

Rich Cottrell, product manager for mixed-service tires, said the

technology's expansion into the G177 "is a no-brainer... a perfect fit. Adding DuraSeal Technology to the rugged G177 will reduce vehicle

downtime due to punctures."

Goodyear G177's aggressive tread design helps provide optimum off-road

traction for mining, logging, landfill, road-building and other severe-service applications. The tire also features high-tear strength tread compound to help resist rubber chipping and chunking. An enhanced casing design helps improve strength, puncture-resistance and retreadability, he added.

Cottrell said tires featuring the technology "logically would move into severe service before it becomes mainstream. We will consider its use in other applications, based on customer needs."

Available in sizes 11R22.5 H, 11R24.5 H and 12R22.5 H, the G177 mixed-

service tire featuring DuraSeal Technology is manufactured in Goodyear's Danville, Va., plant. A 12R24.5 H size will be available in September.
