I simply refer to the fact that many people including myself can not put a 255, or 245 on a 67-69 Dart with an 8" wheel. Nothing more, nothing less. I have them with a 245 tire and it does not work for my car. The purpose of the thread was not engineering requirements but 245 60r15 tire fitment on an 8" wheel which I know from experience can be problematic. I'm sorry if I've offended you by disagreeing, I'm only trying to prevent others from having to do it twice as I have. I find your reaction to my not agreeing with you to be a little much.
