I'm running 35's on 4in lift and raining about 15.5-16.5 but i literally cruise around town. Im not on the gas like a bat outta hell lol. If and when i do drive in a "hurry" i drop to 14 territory. I hate the 3.8 power plant!! gutless gas gussler. i mean i wounded mind the gas range with the power of a v8....Im sure everyone has already said this lol.

2013 jku auto with 3.5 lift and 35" trail grapplers and am currently getting 13-14.3. Summertime will get 14.5-16. Best I've ever seen is 19.1 following other jeeps at 65mph- and usually will get 15-17 highway if not into too much headwind

Well I've got a 2012 2 door, recently jumped from 33's to 37's
My mileage before was probably 18 and now with the new gearing 5:13 it's 15-16
But I'm just getting stated playing with air pressure...
The guys at the shop aired it up to 39 while mounting and balancing but forgot to lower it, so I drove 150 miles on a road trip thinking it was just the new axles and tires
Aired down to 30 for a start and when it stops raining ill do a chalk test!
I think tire selection is a factor here, both weight of tires and tread aggressiveness, I have MTR/K's and used to have Duratracs

I don't even see how this is possible. I'm on 37's with stock gearing, 4.10's, for now and I'm averaging 12. Highway at 65-70 mph I can squeak out 14. It is hilly and windy where I live so that May have something to do with it but you must only drive downhill with a tailwind.
How much does the load rating matter? My 37's are D rated

This is scary, I'm nervous about my 35s and lift soon, I can't even imagine 12-15mpg...
I checked mine on a road trip to compare to what the dash was saying and was pretty close to my math. Highway I'm getting about 23-25, that being said I'm doing 55-58mph on cruise, as soon as I climb over 58 it drops from there, cruise at 62mph puts me down to 20-23.
I did get 427miles to the tank last month.
But I have noticed a drop in mileage lately, maybe that's due to this winter fuel people bring up, don't know much about it.

2014 JKUR, Auto, 5k miles, 4.10 Gears, Rock Hard Engine/Transfer Skids, JCR Dagger Stubby, Bushwacker Flats, 35" KM2's, 2" OME Lift, ProCal = EVIC says 14.4
I've noticed the 'ECO' light goes off when I press the gas pedal and turns on when it I don't. LOL. Seriously, no matter how much I press on it. It's like an indicator that I am pressing Go!
I used to worry about gas mileage but its not worth it, as long as it doesn't take a turn for the worse, just drive that wonderful machine and be happy.
Sure I could baby the throttle, etc, and maybe get a mile or three more, but what a pain in the ars. Easier to just enjoy my machine and take the 14-15mpg.
I'll get better gas mileage with the next generation...

I'm running 37x13.50 toyos that are D rated. They are heavy (92.6 lbs) and weigh in about 25 lbs more than the 37x12.50 MTR Kevlar (68.7 lbs). 100 lbs more just in tires and that doesn't even bring in the factor that I'm running 18's which are typically heavier than 17's. Mileage doesn't bother me too much and I do have a lead foot. My Ecoboost f150 has averaged 14.2 mpg over its 40k miles and that's mostly high speed highway miles. Anytime those turbos are boosting my mileage is crap. When you run 90 on the turnpike, the turbos stay boosted and it eats fuel. Now that I have the jeep I'm going to sell the F150 and get something more comfortable and efficient for my long drives.
