Would like to get an idea the *general* PSI's guys use on the track (yeah, I know, insert a million caveats...but I'm just looking for ball park figures)?

I'm going to, of course, do my own testing (PSI, pyrometer, chalk). For both my RE-11as and 71Rs, I found 32F and 30R hot worked really well, and thought I'd start my testing at that first.

Thanks!

Racing & Competition might be a better place to post this as you're talking track temps.

I run 36-37 hot depending on the track.

Size of the tire also matters.

I run whatever PSI my tires are at when I arrive. I checked it once... back in 'Nam.

This. Which for me usually meant starting at around 29-30 cold.

Also the track bias (left/right; heavy braking zones etc etc) will put more heat into one side or even tire more than the others, so it's always good to simply do a session, get a lot of heat in them, then even them out. Cold they will not be even after you do this obviously.

Ok thanks, I suspected this given the softer side walls compared to the 71rs, or even the 11As, but gives me a really helpful starting point.

Yeah, good points. It's always an iterative process and depending on the track, weather, etc. But having ball park numbers will really help when I also autox, where your tires are starting each run essentially cold.

i typical do 30F/29R cold in the morning and just leave it there

That's my style. As long as it feels good on track forget pressures and focus on driver.
