Tyre popping is eye-popping! Goodyear DuraSeal Tyre survives 367 punctures without losing pressure

While this year’s Mid-America Trucking Show in Louisville, Ky., drew a record number of attendees, The Goodyear Tire & Rubber Company set its own record of sorts during the three-day event thanks to its DuraSeal Technology.

attendees drove approximately 367 nail holes into a Goodyear G394 SST wide-base trailer tyre at the tyre manufacturer’s booth – without any impact on tire inflation.

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

“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 tyre pressure.”

DuraSeal is a yellow, gel-like rubber compound that instantly seals punctures of up to ¼-inch in diameter in the tread area of the tyre. (It does not seal sidewall punctures.) As a nail enters the tire and reaches the tyre’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.”
