I run 38 psi front and 36 psi on the rear with te 275/35R20 setup with Michelin Pilot Sport A/S+ tires. I've got almost 9K on them and they are wearing very well. Only time will tell.

MP4.2+6.0

Front is more of a tradeoff between center wear and cornering scrub off. Currently working around 38-40 PSI, depending on specifics of center wear on the given tires.

Settings are morning undriven temps in a garage (no sun on car) to be clear.

I forgot to add that I use nitrogen inflation. It seems to help.
