I've done a few searches but couldn't find a clear answer to my question. I need to know if a 5.60 X 18 10 paddle tire will fit on an XR650? I'm running 14-51 sprockets so that should give me a little extra room. In the posts I read on the subject I saw some mention about shimming the exhaust? Are there modifications required to make it fit? Last month I spent 5 days at Dumont and was running a 5.30-18 8 paddle which worked really well at first but buy the end of the week the tire was wore enough that I was able to spin it while climbing It is also showing signs of the paddles starting to tear.
