i dunno, im just glad its over. Everything is fine, but he was swearing to me that the stock tire size diameter is smaller than the current size I have. All I could do is say "ok" since he's the guy that owns the speed shop and would never admit to being wrong
If I was you, I would print out the Tire Calc page and bring it to him. You might be helping out another Stang owner by showing him that it is OK to be wrong sometimes.
