My father in law has a 1970 Buick GSX (not real, a clone) with a 455. It weighs just under 4000 pounds, and it has a set of 275/60/15 Nitto 555Rs in the back. He just got the tires this summer, and he and I went to the track several times to get things figured out.
We found that he got the best results (1.7 60' is his best so far, and we think he can still do better) by heating them way up before his first run of the day (i.e. burnout for ~10 seconds) and by maintaining that heat before each successive run (3-4 seconds if he's hot-lapping, more if he has to wait in line).
Call it a misconception if you want, but I'm sharing my experience. Maybe it's not true of all drag radials, but Nitto 555Rs like it hot.
