P85 w/21" rims -- what tire pressure do you use?

    I have a P85+ that stipulates 38 psi front (245/35/21), 40 psi rear (265/35-21).. but I've put Hankook 245/35/21s on all four corners, as well as 8.5" rims on the rear, so all four corners are the same wheels and tires (245/35-21).

    What tire pressures should I use? I assume it should be the same as a P85 with 21" wheels, but my door sticker only has settings for the staggered set up.

    I've had both cars, and believe that the pressures were the same. IIRC
