Tire wear seems really weird. Almost like the suspension is having issues. I'm replacing the stock Bridgestones BT021F's
Yep. Exactly what the worthless stock tires feel like as they turn from junk to utter crap. They'll have you getting paranoid about suspension settings, questioning your cornering technique, and basically losing confidence in the bike when cornering. Get rid of the treacherous doughnuts.
PR3's are good choices.
My favorites are the Pirelli Angel ST's. On my third set.
