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 ran 10.60's with the 20" SS, at 22psi. with good track prep. but they don't last long on double duty.
