If you're trying to extend tire life, I recommend limiting yourself to 2-3 hot laps with a cooldown lap in between for shorter tracks.

I haven't seen temperatures above the 60s, but my tires held well through a very aggressive 20-min run group. No getting slimy.
At the end after a coll-down-ish lap, the tires were 160f on the outer fronts and 130 on the inner rear.
