What's the best tire pressure for my 2012 4.6 sedan on 255/35/20 Fr. 275/35/20 rr ?

Best for soft ride? Cornering? Acceleration? Gas mileage? Traction in snow?

I like about 3 psi above the door sticker recommendation.

I found that on all my cars, 36psi cold is good, 38 start to feel rough and 34 or below start to feel too soft.
I re-inflate to 36 psi once a month.
