What is the recommended "HOT" tire temperature of a Gen IV ACR with Michelin Pilot Sport Cup tires for track days?

Took the Viper to the track - Cold Pressure was set at 29 psi all tires. Checked hot tire pressure after 20 minutes of lapping - Front 35 psi and Rears 37.5 psi. Hot tire pressure readings remained consistent throughout the day.

Thanks.

I suspect your alignment is OE? 38-39 is the target....... if you have a performance alignment [that flattens your contact patch when cornering,] your fronts will heat up better.

I strive to achieve equal hot tire pressures (38 psi) on all 4 tires after each track session. Usually by the end of the second session, all 4 are the same pressure which helps to balance the car (09 ACR). Start out at 30 psi cold and you will be pretty close.
