Truck tire pressure

Just replaced my 2005 F-350 long bed with a 2018 Ram 3500 short bed. Love the Ram, but the ride is not as smooth as the F-350 was. The door plate says 60 lbs in front and 80 in the rear which is what the F-350 called for as well. I would definitely use those pressure while towing. My question to the group is "What tire pressure do you use when not towing and no load in the bed?" I tried 60 all around and noticed a slight improvement in ride, wondering if 55 or 50 would be acceptable. Thanks for your input.

The ride difference may be to some extent due to going from a long box to a short box. Also brand/type of tire may contribute also. The thing with changing tire pressure is that they're weight capacity changes by the amount of air. A tire at 60psi is rated to carry a certain amount of weight. Add or subtract 5psi and the weight capacity changes. So theoretically every time you changed the pressure you need to check the weight. Not very convenient. And the numbers are different from one brand to another.

Thus, long story short, my 2005 ram dually 2wd runs 80psi in all 6 tires, all the time.

The short bed does ride a little harsh, I have a long bed Silverado that says 60 front 80 rear. I run 60 all around when not towing, it makes for a softer ride besides I donít haul anything in the bed but the hitch

Will my short bed truck rides better than a long bed regular cab truck for my model year, 2008. Just to make a point, it is not the bed length but the wheel base that matters for ride comfort.

When using my stock tires and rims in the winter months, not towing the rear tires are set at 45PSI and the front tires are set at 60 PSI. This provides for my truck the best ride.

Experiment on your truck and tires to see what is the best ride comfort for you. Also rub chalk all over the rear tire from side wall to side wall at different air pressures settings to see if the truck tire is cupping or not at these different tire pressures. This way you will determine what is best for you.

According to my owner's manual and the tire safety data plate on the driver's door frame, my fronts are to be set at 70 psi while the four rears are set at 65 psi always - loaded or unloaded makes no difference.
What does your owner's manual and data plate say?
