I pumped my Azenis' up to 40 psi cold. On the track the fronts went to 48 psi and the rears 45 psi. This on a 40+ degree day. I have an AWD Familia. I lowered them all 'round by 3 psi and they felt better. Mates with normal road tyres gained about 3 - 5 psi over cold.
I think next time I will pump to 37 psi cold.
Problem is, should be measuring tyre temps, not pressures. Does anyone have a tyre pyrometer?
