I agree that 35 PSI should not be used for towing. That is why I asked the weight the door sticker has for 35 PSI. I am pretty sure it is not for the GVWR of the F-150. The door sticker will have a recommended tire pressure, but it may not be for maximum cargo carrying. Some vehicles will have several suggestions. The door sticker on my Power Wagon has recommended tire pressures for light loads and maximum loads. The maximum load is the pressure when the vehicle is at its GVWR.

IMHO I'm now thinking maybe 50 psi after driving the 2 miles to nearest Flying J (somewhat warm) should do it... This should put psi about 1/2 way b/t max on tire & max on load chart when cold.
What do ya think?
P.S. Will happily upgrade on next set of tires... Since I only have 2500 miles on these, can't justify spending $800 to replace almost new tires.
Well Ford has a problem (more likely the person that you talked to) if they are saying it takes the max PSI from the tires they are using to drive around empty and they need to be inflated above the tire manufacturer's max PSI to carry a load.
I wouldn't inflate them over 44 PSI cold if that is the maximum pressure stamped on the sidewall of the tire.
