Bead Lock Tire Pressure

I am running a screw blown pro mod car, I have run liners with 55 inner and 5.25 to 5.5 outter pressure. We got a set of Delta Bead Locks and few have told me we need to run 6 to 9 psi.

Is that what most are running with a 17/34.5 Hoosier?

I'm just looking for a baseline to start at.

 

Run between 5.3 and 6.3 depending on track conditions. Normally 5.7 on a good track.

 

Thanks for the response, I am having more and more people saying 6 to 7 I suppose we will just start with 6.5 and can up or down from there.
