Check my truck listed below. I have tires that max wt.is 3750 lbs at 80 psi. I run them all at 55 with empty truck. I needed to go to 65 front 80 rear with a slide in camper wt. of 4400lbs and towing at 3800lb boat. Now the trailer I have has a hitch wt. of 900lbs scaled/loaded. I have left the tires at 55 for several short trips, I think that they should be alittle more air thro and will try 60 than 65 cold psi and see if anything is different. At 55 psi they are not flattened out or cause rear sway. Check the wt. as said by others and try afew different settings, look at the tries to makes sure they are not showing signs of under/over pressure.
