Discount Tire just lost my business
Hell, I've seen Firestone 721s separated coming off the truck brand new. Just like Criterions, Mohawks, and countless other cheapo brands. Gluing rubber to steel ain't a natural thing. I don't care how good your process is. Separation is always a possibility. Anybody that's ever been in the tire business will tell you Firestone ain't ever made a good tire. Although I have seen the little Bridgestones the little Mazda trucks used to come with literally get over 100K on them and still have tread left. People were changing them because they were scared they would separate because they were so old.
