Nitto 555r drag radial track pressure

[Wicked WE4]

What air pressure should I run at the dragstrip? I just mounted a set of Nitto 555r extreme drag radials (275/60r15) on stock rims.

Anyone? Also what pressure should I start with in my airbags?

I run anywhere from 13 to 17 psi in the Nitto's on my Cobra when I race it.

I have been running around 17 psi in mine, seems to work well.

I run19 to 20 with 9.5" wheels. I ran 15 to 17 with 7" wheels, but, I didn't like the way the car felt at speed.
