Edit I got my sheets.
Before session 1, tires cold
F 33 33
R 35 35
After a 25-30 minute session (I did most of my sliding around this session) including a 2 mile cool down lap:
F 37 37
R 41 40
I bled these down to:
F 34 34
R 36 36
After a break I ran another 20 minute session and came off with
F 34.5 34
R 36.5 36
Car was incredible. 75 F OAT these sessions.
End edit
I would have to get my sheets out (I will update this tomorrow if I remember) but the first session I drove I started at 32/33 cold (tires had been sitting for hours) and I think I came off close to 37/39 close to 40 I'm pretty sure. They still felt really good. When I first started to do HPDE I would run them way over 40 hot (this is high 40's hot after a leisurely cool down lap too..) because I was afraid I would roll them over on the sidewall so I was paranoid. They were terrible at that pressure to me.
After this session I bled a few pounds off and the next session I think I came in with 34/36'ish hot after the cool down lap.
In my (limited) experience, They feel best to me when I come in and see around 32/33 or 33/34, but that is after a 2 mile cool down lap, so it is possible they are near 40 during the actual hot laps. I don't have any "track support" (he helps change the tires if needed but then he often sleeps) to check them if I come in during a session.
