I've got a 120/70-17 used Supercorsa that is past it's prime if anyone wants it. I know Bill has said that even used and too slippery for racing that they still work great for stunting. So the first PM that gets to me will get a free old tire.

It's been off the bike for about 2 months so it's got a little bit of a "skin" on it but it should scuff in just fine after a few wear in stops and some S's.
