Here's a chart from Grass Roots Motorsports showing their test data for streetable track tires. To avoid tread compound delamination (chunking and tearing) due to the tread compound over heating on track, use at least -3.0 degrees of front camber, less steer angle when the front tires are at their limit (i.e. avoid temptation to dial in even more steer angle), avoid hot tread compound temps over 200F (come into the pits hot and measure temp data), use a pyrometer to dial in tread temperatures with <= 10F temp spread between inner and outer shoulders. For streetable (DOT legal) track tires, maintain a hot temperature ceiling of <=40psi on a car weighing less than ~4000lbs. Start with cooler cold temps if the ceiling is being exceeded.
Edit: See all of the "care and feeding" files attached and Michelin Motorsports .pdf tire catalog link: https://adzktgbqdq.cloudimg.io/https...compressed.pdf
