I wasn't trying to contradict you. If anything I think I was trying to supplement your statement.
You are absolutely correct. The pressure is determined by weight. The tire dictates the max. pressure based on max. weight. If anything I was simply trying to clarify a very common misconception that sidewall pressure only dictates the limits of the tire, not the recommended pressure setting for the vehicle (or trailer).
If I used the max tire pressure value on any of my vehicles I would be WAY over the recommended tire pressure for that vehicle. That gives a harsh ride and leads to improper thread wear on the tire.
