Okay, not sure if you can see it very well from the pics but I have a small section of tread that doesn't appear to be hitting the road surface. The dealer shoved 35x12.5x20 on factory wheels so my rational is thinking the factory wheels isn't technically wide enough - meaning kinda bowed out? I haven't looked to see if the inside tread 8s the same way but it is on all tires. I'm running 30 psi so maybe I need to increase. Thoughts?
Adding psi will only increase the area that isn't hitting the road. The OEM width wheel with 35s isn't helping any. I'd say you are going to have to live with it. You could maybe try dropping to 28 psi to see if it helps, but you would want to watch the pressure closely, especially in the Fall when temps start dropping.
Or you could buy correct-width wheels for 35" tires and solve your issues.
You can always try the chalk test: lay a good stripe across the tread surface from one tread shoulder to the other, then drive the truck a few yards, stop, get out and look to see how the chalk stripe has worn.
As others noted, the tire's tread surface is being pulled at the shoulders from a too-narrow wheel width for the tire's section width...
And, it is not wise to run an LT at pressures much below 35 psi on the highway. You may of course "air down" for traction when driving at very low speeds off road. Always air up for interstate speeds.
I would suggest a vigorous tire rotation schedule to mitigate the weird wear patterns you think you see. And remember, all tires will feather the edges on the steer axle, no matter how good the damper (shocks) and how precise the alignment. This is one reason for the need for regular, consistent tire rotations. You might try every 2500 miles, for example. It's a lot of work, but you may get more life from this mis-mounted set. Good luck.
I cant tell which factory wheels you have. Are they 7.5 wide or 8.5 ? Your tire size is for wheels 8.5-11 wide, with 10 being ideal. If you have 7.5 wheels you should get new wheels. Factory takeoffs are pretty cheap to buy second hand.

I didn't buy or install these tires - the selling dealer did but I get what you're saying. They have offered to swap the tires so that's what I'm going to do.

These are the optional 20" PVD clad type wheels so I'm not sure what the width is. I will tell you I've never seen a 35x12.5 installed on a factory wheel but the dealer claims they do it all the time.
