While reading the current thread on non-stock tire sizes I remembered this picture I took when I got new tires for the SRT-4 last spring. I thought some might find it interesting to see just how different in actual dimensions some tires of the same spec'ed size can really be. In theory every 215/45/17 tire should be the same physical size but every manufacturer seems to have their own yardsticks.
The Michelin snow tire in the middle and the old Kumho one on the right are both 215/45/17 and are obviously very different dimensions. The new Sumitomo on the left is a 225/45/17.
