My brother just had to have some wide racing slicks for what he called his "Buford" (Ford body with a Buick engine, Hurst transmission, etc.) that he created himself. He couldn't afford good new ones, so he got some retreads. Coming home from Omaha one night, the tread (if you can call it that) separated from the rest of the tire and caused the most God awful racket you could imagine before it finally came clear off and came to rest somewhere along Interstate 80. Believe it or not, and luckily for him, the tire didn't even go flat, but it was the funniest looking tire I ever saw.
