Friday Practice - If you have a set of tires that haven't been heat cycles, go out and run a few 7/10 laps, park the car and pull the tires off. Put on older tires for the rest of the day.
Saturday - If you do warmup, use the old tires. Put on new tires for Qual and R1. After R1, swap to the older set for R2 invert.
Sunday - Swap back to new tires for qual and R3 (also rotate tires at this point), swap to older set for R4.
At this point you've got 4-5 heat cycles on your newer tires. You've still got plenty of life left to use them for Qual and Toyo race for the next weekend, and they're not likely to start falling off until after R3 on the second weekend. After the second weekend use them for practice and invert races. They will fall off after 8HC or so, but if you treat them right they don't fall off too bad until around 12HC.
