You are close, given the variances of tire gauges at low pressures, you could run anywhere from 6 1/2 to 8 1/2 and be "correct"....it also matters whether it is a stiff sidewall, the front/rear weight balance, and how much it gets up on the rear tires for the launch.

If you aren't wadding the tires on the launch, they leave a full footprint, and wear even across the tread section, you have it right.

Sounds like you are having a hot track / tire compound issue to me.

I ease up on the burnouts when the track is hot, as well as running a "medium-hard" (Goodyear D-4A) compound for that purpose.
When the track temps exceed 110-120 degrees, I do a dragster type burnout and roll to the line.
