according to the company.

Attendees punctured the tire using Goodyear's "DuraSeal Popper," a device that enables users to pierce the tread area of a tire by pulling down on a handle. (The tire was mounted on the DuraSeal Popper, but not under a load at the time.)

"The results were eye-popping," says Tim Miller, marketing communications manager, Goodyear Commercial Tire Systems.

DuraSeal is a yellow, gel-like rubber compound that instantly seals punctures of up to 1/4-inch in diameter in the tread area of the tire. (It does not seal sidewall punctures.) As a nail enters the tire and reaches the tire's inner liner, DuraSeal immediately surrounds the puncture to seal the leak.

"If the nail is pulled out, DuraSeal can instantly fill the hole and keep air from escaping," said Miller. "People are amazed that a truck tire can seal itself."
