Almost all the way through 1st tank after putting 38s on doing 22.7 on the lie meter and that includes a 2 hour offroad trip I love this power train

How fast are you going ? What is your final drive ratio ? Is your computer programmed for 38 inch tires ?

From what I have seen those are impossible numbers on 38's unless its all downhill with a wind at your back ...

Or going 45 MPH ...

Or maybe your a diesel ... In which case I retract everything I said ...

Computer is programed for tires not babying it at all mostly city driving other than the short run to the trailhead, about 7mi one-way done at 65mph

Heck mine won't even touch that with LIGHT tires going 65 and mine is geared for MPG.
I could do that and better with the stock 10" 32.2" tires inflated to 38 psi on a day without wind.

Not possible with a 3.6 with that sort of tire (unless the engine was tweaked with intake, tune, etc.) - too much weight, too much wind resistance on the front of the tire (and the truck itself since it would most likely be lifted to clear 38" tires. )
Mine dropped MPG just switching to the Falken A/T tires due to the tread, WIDTH, weight, etc. (and mine was programmed for the Falken tires, verified with two GPSs and odometer.

Diesel I'd believe.

That's why I posted in the diesel forum

I read the title and thought. Yup. .mpg aka 1 but diesel explains the good mpgs

I've always wondered what these would be like with diesel - but no one around here has one to drive.

Now I wonder what I'll be getting when I go to 35s. Looking at the Toyo AT3...
And it's a diesel

I went from 24mpg on stock tires to about 22mpg

Damn only 24. I'm getting 26+. Hoping for 24-25 after.
