Inflation guidelines for towing? (RAM 3500)
I'm still getting acquainted with my new (to me) 2014 RAM 3500 dually. My old 2004.5 2500 had a tire guide that showed recommended PSI for loaded and unloaded. I would always air up to tow and air b...

There is something called a load based inflation index. Based on actual weights, it will suggest tire pressure. Remember that overinflated tires not only give you a rougher ride than needed but may not grip the road as well at over pressure.
Agree, BUT, once the placard is placed on your door pr jamb, the manufacturer won't budge off that, nor the tire manufacturer disagree with the vehicle manufacturer..BUT, the tables are there to be used and they're the owners tires..I've had best luck with dually tires for wear over the last 11 years by running at manufacturers recommended air pressure, but that's based on my own personal experience.
Having worked in the auto tire industry as an engineer for a short time....the tire is NOT considered "over inflated" if it is inflated to sidewall max pressure..The front tires are filled to max sidewall pressure,(80 psi), but rears are only filled to 65 psi..(max sidewall psi, again, 80 psi
Sometimes when working more with trailers, the load tables are more proficient with tires and air presses as opposed to one's pick up truck...but..not my truck, nor my tires.
