You learn something everyday. I'm pretty anal about tire pressures but never knew that the placard on the door jam were "max" inflations and that the OEMs actually recommended different (lower) settings for other operating conditions.

My typical habit is to set pressures 1 or 2 psi above the placard to offset seasonal pressure losses and get best mileage on my highway vehicles.
