275/40-R20 Mickey Thompson ET Street S/S: what PSI at the track?

The title says it all. I JUST installed 275/40-R20 Mickey Thompson ET Street S/S on my 2017 Charger Hellcat. I am running about 30psi on the street, but no idea what ballpark I should start at when I get to the dragstrip.

Your thoughts?

I have always ran 18-20 psi with my 275/40/20 MT ET Street SS.

So are the 20" drag radials worth it or a complete waste of time and money? I'm considering them also. I just want something stickier than Michelin PS 4S.

Absolutely worth it. Ran 10.92 with them, no weight reduction, bone stock, mounted on oem wheels.
