Tire Pressure Not Towing

[Jhurk]

I have a 2014 Dodge Ram 3500 20" tires. When towing I run 80psi in rear tires and 65 in front as per tire specs. Now when Not Towing I want to reduce rear psi to 65-70psi to,reduce bumpy ride. Any thoughts, any buddy doing this?

There should be tire pressure on your door sticker, but my 2008 wants 40 or 45 when unloaded. I run about 50 and do not notice a difference between that and 40.

Go to your tire manufacturer's website and look for their tire inflation guide here is Goodyears guide.

20" tires have the bumps built into them. lol
I run the same pressure towing and not towing 70 front and 65 rear per the door sticker. Have towed all over the US with no issues.

Not a 5er here but run 80 towing and 40 when not towing. Also run 40 in the bags towing and 15 when not towing.

Haven't noticed any unusual wear at all and is much smoother driving.

Not towing I run 60 front, 65 rear. Towing I run 73 front, 80 rear.
