With my driving style they were settling at the same hot temperature here (At Zandy)
It's pointless setting tire pressures around cold temps, as it means your setup will be ruined after a couple of race laps.
Given how hard I am on tires around here I expect I was reaching 41 or 42 Psi after 4 or 5 laps (optimum pressure is 40 remember, and not really achievable for me if I was to maintain a fast pace) as I use the tires as one of my main braking methods anywhere that doesn't feature a straight.
The left rear was practically melting after 5 so I drove most of the race very carefully apart from my stupid Lap record attempt
