I did. When I was trying to decide between a 225/45 or a 235/40, I wanted to be as close to stock in diameter as possible. That calculator showed that the stock diameter of a 215/50 16 is 24.46. The 225/45 is 24.97 and the 235/40 is 24.40. The 235's were closest and that's what I went with and haven't had a single problem.
