I have run the tires 32/39 like the door plate suggests which gets me 1200/32=37.5 in.² and 1600/39=41 in.² contact patches. I just installed brand new tires and with the way I drive I tend to scrub the outer edge of front tires I think I'm going to add a smidge of air.

1200/36=33.333 psi
1600/40=40 psi

1600/32=50 in.² (nine more in.²). Prob would be good for acceleration but not great for tread wear.
