Making a mistake?

So Its time to buy new tires Ive always wanted to go up in size. I currently run 285-75-16 falken tires and my plan was to go up to 315-75 (or 70 i cant recall) -16. The new tires are going to be toyo open country ALL TERRAIN. NOT mud tire. But now that the time has come to move up I am reading terrible stories about gas mileage. Right now I get about 14 city 18 highway and 16 combined. how much will this drop? whats your guys experience? I went with an all terrain to try and keep some mileage. whats your guys experience jumping from a 33 to a 35?

No matter how you look at it, you're going to lose some MPGs. I don't think you'll notice a big difference between mud tires and all terrains. Check out the Goodyear Wrangler Duratracs. Good looking tire, almost identical sidewall to Nitto Trail Grappler MTs but has a less aggressive tread and a much quieter ride.

I have an 04 (6.0l) short bed and 35s. I usually get between 230 and 280 miles out of each tank, depending on how much I idle and if I haul anything.

For me, the best AT is the BFG MT... Always keep in mind that the tires for these trucks has to be E rated. I use D, NEVER C!. I dont use my truck for heavy town or put to much stuff on the back, so D is OK. If you load it, use E. 50psi.

Long Bed is 39 Gallons
Short bed is 28 Gallons

600/39= 15.4 MPG
280/28= 10MPG

Tunes should help

I'm getting about 325-350 miles on my short bed truck!

Before my 35" TOYO tires I would get 425 miles tp the tank!

i have a bulletproof egr cooler, catback exhaust 4 inch, with deleted cat, aem brute force intake, and custom tunes from vivian, via sct xcal 2, i think the tunes do most of the work, but yea, i do a fair amount of highway driving usually doing about 80 mph and average 600 miles per tank. but i also have a 40 gallon tank, i know some of the f350's came with like a 28 gallon tank...I also think i could get a decent amount more out of my tank if i didnt bomb down the highway, but i got kind of a lead foot that i cant seem to cure....I actually average about 18 mpg's, i never use a full tank, when i fill up its usually about 33 gallons, give or take a little bit, so im squeezing 18 mpg out of my 6.0L so im happy with it.
