I probably have more pin weight than anyone posting so far, 4,500#. Weigh your rig loaded and unloaded. Use the tire inflation chart associated with your tires.

I run 80 in the front all the time is is a bit high on the chart but it averages out for the edge wear fron turning.

On the rear I run 55 loaded and solo 45.

My truck is a 3500 RAM Dually.

If you are running 80 in the rear with a dually your rear tires will be bald in the center in no time and I would hate to ride in your rig!

I an still wondering if you have the biggest load posted and run 55 lbs loaded you are not even up to a D tire load range??? Air pressure carries the load!! "what say you" and this is just a discussion for all of us. I see less heat on our G tires on the alpenlite at higher air pressure as it builds up towing on a hot day and same tire will be the coolest.

So it seems like your lower air pressure tires would be kinda hot?

They are the same temp as the front tires when towing. No heat gun just my hands, I always do a walk around and touch each tire when I stop for fuel or rest area.

Look at the tire pressure table associated with your tires, if I ran any higher psi I would be wearing the centers out.

My door says rear axle max load 9350 @ 65psi my rear weighs 8,460 I run 55psi

front max load 5,500 @ 70psi my front weighs 5,140

So based on what your saying I could run D tires on the rear. I agree but I have personally seen that the tires wear out extremely fast!
