18" Staggered Wheels: PSI Question

I got 18" staggered wheels on my e90 and I recently put on Michelin Pilot Super Sports.

User manual states I should run 36psi front/42psi back for extra load. I ran this on my old NITTO NON RFT Tires (Softer tire from what I experienced) and the fronts had shoulders wear off noting that they were under inflated.

I wonder 36/42 is for RFT's and if I should run higher for these NON RFT Michelin PSS's.

Any input?

Thanks in advance.

So basically, should PSI be higher on NON RFT's compared to similar spec RFT's?
