Default Tire pressure 255 40R17's

Hi All,

As that is NOT a stock tire for an '04 WRX, what pressure should I be running (on 9" wheels)?

Owner's manual shows 36# front, 30# rear, for 225 45R17's. That's my only reference right now.

TNX!

Well, easy for you to say except there are different pressure specs for different sizes, in the manual, to wit:

P195/60R15 87H, 6" Wheel, 32# F, 29#R;
P205/55R16 89V. 6 1/2" Wheel, 32# F, 29#R;
P215/45R17 87W, 7" Wheel, 33#F, 32#R;
P225/45R17 90W, 7 1/2" Wheel, 36#F, 30#R.

I figured so many are running larger wheels/tires someone could chime in on what they run, but I'll call Tire Rack tomorrow.
