NRFT or not, should the tire pressures still match does on the door frame and manual spec? OR do these tires require a different, higher tire pressure (PSI)?

Thanks
Whoa! Check the label on your driver side door.

Tire pressure should still be the same, RFT or non-RFT, doesn't matter.

With that said, I have Hankook Ventus 12 at 235/40/18F, 265/35/18R and I increased the pressure slightly, running 35psi front and 41psi rear for the occasional run up beyond 100mph. Yellow label on my door indicates 39psi front and 45psi rear for speeds up to and beyond 100mph for our rides, regardless of tire type.
