Don't go by what the manual says, Go by what the tire says. Put about 5-7 pounds less than the max psi (written on the sidewall) in it since the temperature is warm in your climate. I keep my tire pressures even all the way around but you may like having a little less in the front to make the ride a tid-bit smoother.
Always stay withen 15 PSI but no more than the max PSI on the tires to keep the treadwear consistant.
BTW, I have the exact same wheels as you.... And the exact same kind of car (except alpine white) Beautiful isn't she?
