Mileage MT vs. AT?

Hey
I recently switch from a 265/75/16 AT's (31.7" when checked, I don't remember who's) and went to a 235/85/16 (32") Hankook Dynapro M/T's mounted on the same rims. I have not noticed a difference in mileage (still sucks) but I did notice a slight bit more noise (to be expected) but handling, braking, is better and so is the ride (firmer) and these are rated E; instead of D, which gains me load carrying capacity. It also seems to have better git up and go from a dead stop, I suspect less rolling resistance due to narrower size. So far I like these tires and was glad I made the size change.
P.S. Some years ago I went from a 33/12.5/15 BFG M/T to a 33/12.5/15 BFG A/T on a Suburban w/ a 350 and gained 2 MPG.

I would like to do a back-to back test of this commonly accepted ‘fact’ to see what the actual difference on the subject car truly is. Something like a BFG MT or Maxxis Bighorn MT vs. a conservative AT like the Maxxis Bravo AT.
I have the parts but would need to pay to have my Bravos mounted on my stock 4Runner wheels (which are currently naked) then spend the time and fuel to run repeatable tests.
I think a lot would depend on the car and tires being tested. There are always lots of variables even when trying to do a semi-controlled test, but it would be cool to give it a try and create some data.
Similarly, I would like to do a MPG test of the same tire treads in both a narrow and wide section width. Say 255/85R16 vs. 285/75R16.
