Michelin PSS only lasted one autoX season :(

Hrm looks familiar...

They got too hot... Michelin PSS are great autocross / street tire because they come up to temp quick and stay at temp unless pushed, once pushed (like a road course, see above comment about laguna seca) they get too hot and start chunking like that on the edges.

street use won't heat them to the chunking level, and autocross is usually too short for them to over heat.

2 years, 24k miles, 14 track days (autocross roughly 12-20 runs/day) on my set... but I'm on a square rotating setup.

No offense but I was never a fan of those tires.

I'm gonna run the shit out of mine tomorrow let's see how they do ...and all ready have one optima event on them in 105deg heat and one 2 day hotchkis event

None taken. I loved them when I first had them, but as they were being heat cycled they seemed to lose their ability to get up to temps for autoX events. I could never get them to generate any heat like I wanted as latter half of the autoX season was happening. I Think they are a great street tire but I don't think they make a good autoX tire, but they are ok as a choice of compromise.

Yep. Looks familiar except mine is worse. This happened in just the last autoX event on concrete. The sidewalls are thin in rubber and they start peeling and rip chunks out.

Nearly 200 runs - plus the other use that you mentioned - in a heavy car with a strut front end is pretty damn terrific.

That being said, you might do even better by optimizing the camber and playing with tire pressure. A few less PSI might not feel as good behind the steering wheel, but the additional grip could reduce wear by not allowing as much slip. It really requires some experimentation, though, as it's dependant upon the surface and your driving style.

So true. I go through 2 to 3 sets of tires a year but run a lot of events.

Not looking to bad talk the tire because it was a great tire up until just recently.

No, all asphalt, but on some bad surfaces that can eat the tires. I did notice some small little divits now higher up on the shoulder block butnot on the edge. These may have been there from some hot days and temps running optima road course and auto x ( I didnt have them then) and didnt see them before.
