what is the tire PSI supposed to be?

I run 31 psi all around during commuting days.

I just bought some 16 in rims with 205/45 Hankook Ventus HR-2s and I was wondering what PSI I should run them at. The max psi on the side of them is 50 but I think if I set it at the max they'll probably wear bad and that is something I really can't afford to do since they are 55,000 mi tires and I actually want to get that out of them unlike my stupid old General Exclaims which I got 20K out of instead of the 40K I was supposed to.

The pressure shouldn't affect wear much, but it will definitely affect your ride. Between 35-40 psi seems reasonable to me depending on the roads in your area and how harsh a ride you'll tolerate.

Underinflated tire will wear quicker on the edges than in the center while an overinflated tire will wear quicker in the center than the edges. I don't know how over/underinflated it has to be for uneven ware to be noticable and I'm guessing it depends alot on the tire.
