SG Door car tire pressures

Same pressure hot or cold? Don't your cold tires coming off the trailer heat up enough to add a pound from the first burnout?

I'm trying to get to about 9.5 pounds immediately after the burnout. That's why first pass I have set about a pound lower.

Am I doing it wrong?

my 33.5x15 stiff wall goodyears increase approx. .75 to 1.0 lb. From cold to hot. I run 10.0 lbs. Hot, 3200 lb. Camaro.

We alway run 7.25lbs, hot or cold. 1971 Challenger, 2640lbs w/driver, 33x16 Hoosier tires, runs 155mph.

If you can run more air, still cut a light and not spin - then your better off with more. Our car happens to like it in between 7 & 7.5.
