nitto 555r ?s

i just got some nitto 555r drag radials for my 89 gt and was wounderin what is a good pressure to run in them for the track to hook real good????????

When I ran my old car at the track with Nitto's, I played around from 14-17 PSI depending on weather temp and track conditions.

I'm pretty sure the regulator on the gun was built for high pressure, so stick with high pressure tanks. with a low pressure tank, you will most likely run into consistency issues. just because the gun operates at low pressures doesn't mean that you should use a low pressure tank.
