Heavy tires are a mpg killer too, LT’s are much heavier that P metric.

I hadn't given that any thought. Good point!
My new DMax is leveled it looks great but the MPG are less than I would have expected for a tuned deleted truck, maybe this plays a role.
Gotta love a diesel though, 14mpg around town and 14mpg pulling a loaded 30' gooseneck down the interstate.
