2wd Tire size for best MPG

[Kevin 007]

I through on a set of 285/75/16's BFG all terrains that were laying around onto my 84. brought the revs down a bit but more rolling resistance; so mileage didn't really change. I do a lot of highway driving so I will be leaving them on just for the sake of loosing a few rpms...

Is that after recalculating your distance traveled?
