it sounding like the 50 psi so far is a bit too high for these tires. They are rated at 3190 max. Well my truck weighs about 5800 lbs, so i dont need anywhere near the max.
Im going to drop them down to 40 or so and see how they do.

40 is about what I have always ran in light truck tires.... unless I am loading it up real heavy...

I know there is a formula out there someplace, but I can't find it. From what I read the larger tire with a heavier load rating can actually be run at a lower pressure, I think like about 5 %.
I'm running 42lbs in my tires...
My E-Rated Michelin's (Same as Nick) seem to be perfectly happy there.
My stock tires up front (with a max rating of 44 - 45 PSI) also seem to be wearing decently... Though, they skid a lot in low speed stops

Maybe I should lower mine and see if these tires will last a REALLY long time.

The door sticker is the rating based on the stock tire. Given tire manufacturing changes through out the life time of the truck, the sticker can be wrong. Changes in formulas, compounds etc, manufactures can make better tires. ...Ok enough with my BS....
Go by what is on the tire, not the door sticker. Next, when reading the recommended PSI, this is for the MAX weight load capacity the tire is designed to carry. If you are not planning to use the tire at its max load capacity, you can lower the PSI. As what Brian and Nick stated, you may want to drive a bit through some water and see what the contact patch is looking like. You want a nice even surface though out. Too much air and as Brian and I have experienced, the outsides will cup.
So you will have to play around to see what the front and rear tires are happy with. IMO, I try not to go more than 5-10PSI lower in the back than what is in the front.

It shouldn't matter who made the tires, This is an industry guide line.

A friend of mine once said "I don't let (tire manufacturer) tell me what kind of oil to put in my car. Why would I listen to (car manufacturer) when it comes to my tires."
Things are a lot different nowadays with tire sensors and such. In my 10 plys I run around 60, if Im gonna be loaded down Ill bump the rear up to 70. Ive had great wear on them this far.

Go by the tire, not the door.
You bought 10 plies, not sure why, but you need to run the higher pressure for tread life. I have learned the hard way, running 35-40 in 10 ply tires. The edges wear faster, and will cup.
I run 60 in my 10 plies when unloaded.
Just personal experience, I am not throwing this out there to be flamed. All of my 10 plies have been on heavier, 2500s. I have never gone over a D rated tire on ligther trucks because they are heavy as hell and not needed. I like P tires on my half tons.
