    Depends on the tire not rim
    Go with tire manufacturers recommendation

    Michlens run better lower pressure

    This one is kumho tires. Not my favorite but they are as new. For now it'll do.
    Thanks

    Just take a guess and see how it feels
    32-32 then go from there

    I run 35/35 on the street and 32/32 on the track where the tire gets hotter.

    I've got 34 but was wondering what others were doing since I had no chance to take this car to track.
