Has anyone squeezed some larger tires on the rear of an M4 HT stumpy (2003)? I would like to try bigger than my 2.1s that are on their now. I am looking at getting some 2.35 Panaracer Rampage's. Let me know if any of you have had experience with bigger tires on a stumpjumper. I live in MN and we don't rider trails when they are wet here so mud isn't a problem. But I would like them to have enough clearance so I don't trash the stays.
