Oh that old bit, somewhat circular thinking on your part. It seems more likely that the camber setup was too much, though it is hard to believe due him coming through the field a few times during the race. Running four tire stops thus having fresher tires than anyone else. Also Kahne ran a similar strategy and even at cruising speed cut down a tire. So how is it that an equally hard running Biffle on older left side tires didn't run into the same issue. Also it was a left blow out/cut down, meaning that debris was more likely the culprit because the wear rate at Michigan is quite minimal on left side tires. Hence Junior running as fast of laps before blowing up with left side tires 130+ laps old. Yet this clearly means nothing because JJ's word is absolute and he couldn't possibly be mistaken.
No reason to be sarcastic about it when you could handle it in a more debate fashion, rather than trying to demean with a false analyses of why I'm wrong. Also read the articles they two claim it cut down which means more likely debris than tire wear was the issue. Further more people do lead lives beyond their couch, such things that provide them with insight on to why it was probably bad luck that he doesn't want to admit to.
