Dually rear tire psi. What is correct?
 

I am getting uneven tire wear on my rear duall's. The outer tire seems to be wearing more quickly than the inner even though they are the same PSI. I tow a 5th wheel often so I usually just leave the rears at 65psi. Should I be running less air when not towing and should the inner/outer psi be staggered at all?

Thanks for any input

I believe 65lbs. psi is the max. as indicated on the door sticker. Inner tire wear is normal. Meticulous rotation is the solution that I have found.

I run 30 in my rears to get them to wear evenly. The outer tire will wear out faster than the inner unless you rotate them.

the sticker on the door says 45 for light load and 65 for max load

Tire guys say 25-30 psi when empty if you don't want to wear the centers. I'm about 29 or so.
