I found this tire in the trash pile at a race weekend.  A club racer gave it up for dead.  The vendor let me have it for a test.  When a tire is this bad, it’s difficult to adjust the suspension, rider and/or psi to solve the problem.  I wondered if putting a destroyed tire onto a properly set up bike with correct psi could clean the tire up. Here it is, mounted on my 600 riding at 90% at CVR after 10 laps:

It’s not the tires fault, it’s your suspension.
