I put my PSS back on for a track day this week with morning temp in the 30s and afternoon was 50s. They did surprisingly well at the track for a max performance tire. No chunking and no overly greasy feeling. Even the tread seemed to hold up like I would expect with the 300 rating. I ran hot pressures at 39 front, 40 rear and tried 38 front, 39 rear later but I think I liked the slightly higher pressure more.

On the street though in 40-50 degree temps (and normal tire pressure 35/36) I'm getting a lot more wheel spin on corners and standing starts than with my Michelin PA4 winter tires.
