I'm pretty sure I know the answer to the following question, but I'll ask anyway...just to be sure. When I took off my stock Potenzas last Fall, I didn't pay attention to which wheel came from the front, and which wheel came from the back. While I'm not going to be putting them back on for a little while yet (l live in Maine), I was wondering if there is anything I could look for that would indicate whic tired went on the front and which went on the back. I know...dumb question. But like I said, I had to ask.
