Nitto NT555R 315 drag radials, what tire pressure?

[KenneBell]

I've got a pair of nitto 315 drag radials, what pressure would you reccomend? I drive around on them so 8psi is probably out of the question but something that I could get decent traction and also take a turn and not worry too much. Thanks

Any suggestions?

18 psi

whenever i go below 15 hot in my nittos they cup and traction goes away. 15 is where i run my 16s and 15s but everyone seems to run 17-18 on the 17s
