The correct pressure is load-dependent. Too high and you get excessive center-wear on the tread. Too low (worse) and you get sidewall heating and side-wear on the tread, and early tire failure. The pickup truck tires are rated at 80#, but they only have that when the camper's on it. I think 50# is more of an unloaded rating, or 65# as a compromise. I believe the owner's manual (that un-read rag!) actually has a chart in it.
