Newer member, glad to see tire pressure is almost as controversial as the type of oil you run. LOL

American Racing wheels are only rated for load range E tires @ 65 PSI. This is for the 17" Baja dually wheels (the only ones they offer for a Ram 3500 DRW).American Racing wheels
Charts are general guidlines. It doesn’t mean squat. You need to do a chalk test to see how your tread pattern meets the road surface.
Here’s how to do the chalk test:
Load your vehicle as you plan to drive it. Adjust to your desired tire pressure. Drive around until tires are at operating temp. Find a smooth asphalt surface for test. Rub chalk across tire tread until your tread is covered with chalk drive forward just enough for one revolution. Check to see how chalk has changed. If chalk only removed on outside of tread, your under inflated, only the center over inflated.
Jeepers do this when installing bigger tires since there is no “chart” for your specific setup.
Try it, you will be surprised at the results.
