I'm having a bit of a problem keeping tires on this bike, I've changed the rear shock and it is set for my weight. And I will admit I'm a little ham handed and love to do wheelies, but a Pirelli angel gt is only lasting me about 3k miles. I could get at least 5400 out of that tire on my gsxr 750, wheelies and all. Anybody else having a similar issue? I check tire pressure every time I ride, front 36 rear 38. Any advice would be appreciated.
