I just ran them last week at a porsche autox event and they did great! After about 4 runs with about 5 mins in between each run(74 second course) they were at 39psi hot. I started the day at 35psi cold, but bled them down after the first session, if I had to guess they started at 31psi cold at the end of the day.

 

FWIW, I don't track my car. When I first bought them I had them at 35 psi cold. I noticed that I was nowhere close to the pyramid even after moderate driving so I dropped the pressure. I now run 32 psi. My tire size is 225/255, running them on AP2v2 wheels with a stock suspension.

 

at deland on my ap2 staggered setup with bridgestone s04s i was running 31psi hot all around and the triangles were still not being scrubbed yet. hell, i started at 34psi and kept dropping it and the car loved it.
