24 cold should warm to 30 hot within a few laps. They have an extremely stiff side wall, so do not worry about starting at 24 cold. Don’t let them get much higher than 32 because they tend to get greasy.

I´ve done two days and went with forum member DRPM recommendations of aiming for 31front and 32 rear hot. A few sessions they went up a little higher but still gripped really well.
I´ve runned NT01s for the last few years and ran those 33 front and 35 rear.

Good info, thanks. I'm used to a completely different tire, the AD08R, and run them at a 2 PSI differential of 33-34 front and 35-36 rear.

C course has a very fast and somewhat long right hand sweeper. As a result, I had 1 spa lower on the right side, and ir was a very warm day.

Passenger side: Cold, Front 25, rear, 24...Hot Front 31, Rear 31

Driver side: Cold, Front 26, rear, tires 25...Hot Front 31, Rear 31

The tires only got squirrelly when I got that way. �� Wear looks good. 6 heat cycles over the weekend, very consistent, not big drop off in performance as I have seen in Hoosiers, as they cycle toward oblivion in about 10 heat cycles, in my experience.
