RFT vs Non-RFT Air Pressure Question
The Basic question I want to ask is:
Should PSI be higher on NON RFT's compared to similar spec RFT's?
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.
