Your tires will have a cold psi max on them, I usually keep mine 10-20% lower than the max, my stock size are 50psi max and I usually run them between 40-50psi cold. The higher the PSI the better the mileage but rougher ride, vice-verse for lower mpg/smoother ride.

On mine the manufacturer specs are 35 in the front 41 in the back, but I usually run them at about 45. Unless I'm towing then I pump them up to 60 front and 70 back
