What does the placard list as your tire pressures?
Unless I am misunderstanding the OP, the psi embossed on your tire is not the controlling number for your tire pressure setting--the manufacturer's posted placard (usually near the drivers seat) is what you should use as your tire pressure setting. Different models, will often have different posted tire pressures. You can use Hankook's tire inflation tables for any adjustments based on your corner and/or axle weights.
