Agreed. I run 37-38 in the front on the street, because I do tend to take corners fast. When I first tried less than 37, I ended up scrubbing the sidewalls, and the corners were wearing faster than the center. Even with most of my drive to work on the freeway. So all the variables you listed, including driving style. If you don't push the limits of the tires that often, then 32-34 should be fine.
I ran 1 set of kumho mx 225/50-16's, and those I had to run about 35 front, 32-33 rear.
I also rotate my tires every 2 months... or after 2 autocross events.
sounds good to me. but i dont get why is the back require more pressure then in the front on the contours?

It doesn't. The rear requires less because there is less weight on it. However, you can keep them the same with no problems on the street.

the 185 70 14 and the 195 65 14 requires 34psi all around. the 205 60 15's says 31psi in the fron and 34 in the rear. thats what the sticker says on the door. but im gonna go with 32 psi right now and i'll watch the tires for wearness.

That doesn't really make sense, unless they're assuming everyone will be driving around with 1000lbs or more in their trunks. As soon as you start putting more than 32psi in the rear, you'll see the contact patch begin to shrink.

My contour w/ 185/70/14 says 32 all around.
I'm not sure about how they decided it for the contours but sometimes the manufacturer has pressures listed for half load or full load.

Another example of door jam stickers vs reality:
I put Falken Ziex tires on my wifes Intrepid. I left them at the door jam specified (and Discount Tire filled) 32psi. After about 6 months, it was apparent that 32 was WAY too low for those tires, as the shoulders were wearing fast. Had the alignment checked, and it was good. I've since upped her tires to 37 front, 34 rear, and they seem to be wearing a little better. It might be a little too much, but it'll help even out the tire wear (put more wear on the center).

Big Jim... when I meant the pressure inside the tire should never exceed the pressure on the side, I was refering to it being cold. Just to clarify.
