Rear tire pressure dually
Just changed from a TT with 1200lb tongue weight to a fifth w approx 4000 pin weight. Haven't gotten to the scale yet. I'm confused.... placard on truck door says tires rated at 2660lbs at 65psi for r...

I'm running 65 psig cold in the rear tires of my dually when towing the 5th wheel in my signature below. According to the TST 507 TPMS, pressures will increase and stabilize around 4 psig above cold inflation pressures at ambient temperatures of 90 degF or so, and tire temperatures increase about 6 to 7 degF above ambient temperatures, depending on road surfaces and which side of the rig gets direct sunlight. (An interesting observation - to me at least. The inside right rear tire is closest to the exhaust pipe, and it will run 5-8 degF hotter than any of the other 3 rear tires when making a long pull up a grade while towing.)
65 psig is the door sticker pressure recommendation for maximum rear GAWR. The E-rated tires are capable of 80 psig if needed.
