The 367th puncture still did not cause this DuraSeal trailer tire to lose pressure, Goodyear claims.
LOUISVILLE, Ky. — Goodyear subjected a G394 SST wide-base trailer tire with DuraSeal to torture at this year’s Mid-America Trucking Show, and has now announced the tire survived the ordeal.
The tire was punctured 367 times without losing pressure, Goodyear claims.
The tire was on display at the show and visitors were able to use a ‘DuraSeal Popper’ device to pierce the tread area with a nail. The tire was mounted o the DuraSeal Popper, but not under load at the time, the company says.
“The results were eye-popping,” said Tim Miller, marketing communications manager, Goodyear Commercial Tire Systems. “DuraSeal Technology is the industry’s first and only built-in tire sealant, and is designed for multiple punctures while maintaining tire pressure.”
DuraSeal consists of a yellow, gel-like rubber compound that’s released when needed to instantly seal a puncture of up to a quarter-inch in diameter in the tread area of the tire.
“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.”
