After the first autocross in my 981 BS with PASM in not-freezing temps, I noticed that the outside shoulder of the front wheels were showing more wear than the inside. Attached is a photo of the left-front 20" Pirelli Pzero (the right-front outside shoulder looked identical). Started at 33PSI cold and they crept up to 35psi hot. I'm not sure what the alignment is, but it should be OEM. The rears looked more even.
Grip started to get pretty good until they overheated and got pretty greasy. Just wanted your feedback if wear like this can be caused by running too low of a pressure, and how much increasing the neg-camber would alleviate this.
