I keep my front tires at 65psi and my rear tires at 80psi.

I honestly think that is just backwards from where it should be.
Especially if you are running the diesel engine versions.
Those engines are HEAVY and front tires are always carrying that load.
Keep the front's aired up good. I had cupping and wear troubles on the front tires for my 2011 Ford dually cause I ran them like the dealer had them aired to, which was actually way too low.
Started running them at 75 PSI instead of the 55 PSI and wear/cupping troubles went away. Front tires here.
Back's at 65 should be fine.
