Warren,
No, the tire had never had any problem and the former owner said he had never had anything done to any of them. I have had tires blow out back when we had the old bias ply, but nothing to compare to this. Oh well, at least I got a lot of attention and probably several brown pairs of shorts in the cars around me. No curb where I was turning. Just off one very level street onto another.
Believe it or not I still play with that old lap top from time to time. I bought a new Dell several months ago and have hardly used it. I should get it out and hook it up and let it update itself.
