You should use the pressure on the door jamb, MOST OF THE TIME.
There are exceptions.
My 2007 Tundra was one of those exceptions. With the pressure at OEM recomendations, the front tires wore terribly on the outer edge.
The alignment was right on but the wear was still there. A guy at the alignment shop said to kick the pressure up to 42 even though toyota said 33. I tried it and the truck handled better, rode better, got better gas mileage, and the tires lasted longer. No downside.

I'd say it's a case by case decision taking into account the type of vehicle, the design, the tire wear, handling, safety, etc.
But if in doubt, use the car manufacturer's rating.
