CHICAGO – Bridgestone Firestone North American Tire LLC’s (BFNT) Greatec wide-base medium truck tires now contain the company’s proprietary Turn-In Ply (T.I.P.) bead technology, according to Modern Tire Dealer magazine.
“With each revolution of a tire, the sidewall flexes in and out, increasing heat build-up,” said BFNT officials. “If a tire is underinflated or overloaded, the heat build-up is extreme and the end of the body ply can separate from the rubber surrounding it.”
