Low profile tire like that, start @ 25 PSI, and work your way up/down from there. Probaly will need to go up, but every car is gonna be different, especially *** end weight.

What you can do is drop your tires to @ 25 PSI, and do a pretty good burnout, right there in your driveway or what have you, and soon as you finish, hop out as quick as you can if you don't have a friend with you (which obviously helps if you do), and feel the tire. Looking for the tire to be hot across the WHOLE tire.
If TOO much pressure, it will be more so in teh center (tire will "bow"), and if not enough, it will be hotter @ the outer edges. (tire will "cup").

AND, if you are fortunate enough, you can actually LOOK at the tire marks on teh ground. If it is blacker on teh outer edges, not enough pressure. If darker in center, too much. Uniform across whole tire, perfect.

Tire like that, with more sidewall than teh above mentioned tire, down to @ 14-16PSI, and same thing, go up/down as needed.

You want to run AS MUCH tire pressure that you can, and STILL hook...remember that.

That is the key! Less rolling resistance, better times. Sometimes when you spin, people assume to drop the pressure. You may already be too low and cupping a radial tire (not the same as a slick), so sometimes making 2 or more runs at a certain pressure is needed to verify the results (not being in the groove, too small or too big burnout, etc).

tire pressure regardless of size and type of tire depends on vehicle weight, how much power you are making and how well your suspension is working.

I ran those exact tires at the track. I had them around 18 psi, 2k launch and bogged... So I say 18 psi with a 3k drop... 2.1 60' stock ws6
