I remember those years well. I had a 75 Corvette with Firestones on it. Had a blowout and the tire ate up the fiberglass.
Bridgestone is Firestone with another name.
The Bridgestone plant where the problem supposedly originated:
Bridgestone Americas Tire Operations
3001 Firestone Pkwy NE Wilson NC 27893
