When I raced on Pirellis, the rear was set at 18lbs cold. That is definitely cold tear. It comes from tire not up to temp, and you are hamfisting the throttle.
Smoother throttle application, tire warmers, and lower PSI will all help.
Also you may need to see Barry at KFG to set your suspension settings. Ive had plenty of race day tires look like that.
The ridge is pretty tight in places, and has some high speed sweepers that will tear up a tire.
Again, get with Barry, he can help you.
