What Holger said 
Maybe I should clarify, grip is still good for a street tire, but what I wanted to say was that it seem to drop off noticeably after a few hard laps.

Canyon is right, PS2's get greasy after a few laps (like all street tires). I used to run them in the low 30's hot, but even that didn't help much.
Maybe us Left Coast guys just push harder.

Its always interesting when this topic appears as there seem to be so many answers to the question of tire pressure. I've heard 36/42 cold on PS2s. I have even run that pressure cold and have not experienced substantial slipping on hard cornering, even on track. Well, I will now try dropping it and see if that makes it even better! What do I know, I sell insurance...

I ran my PS2's at 36/38 hot yesterday at Lime Rock with SCDA. There four, 25 minute sessions, and I found at 36/38 hot, the tires starting loosing their grip after 15-20 minutes. I'm going to try 34/36 hot next time if I don't have cups on by then. Again, thanks for your help.
