I see about 14mpg around town with 40"s and 5.38 gearing.

18.124 overall average since 04/23/2008. That includes city, highway and towing several times in the Rockies.

I am satisfied with it. It beats the 12 I was getting with my 2004 Hemi Ram 1500.

I just lifted my JK 3.5 inches and added 33in mud terrain tires. I'm not sure what my gears are but it's a sahara...and i've never changed them. I'm continueing to drop...went from17.4 on the way home to 14.1 today (six days later) and every time i drive it it slowly drops 0.1-0.4 mpg!!

hmmmm

I'm rolling 35's on the X 3.21's and getting better than that......average about 16 after Flashpaq and can hold highway speeds except for big hills. Are you hauling sand bags in the back seat or something?

Big heavy mud tires will kill you if you run high speeds. I get 14 interstate with AT tires and 12 interstate same size MT tire on same wheel. I get about 17.5 in town and normal daily driving.

I get 14mpg with my 35's and stock gears and I only drive to school and golf practice and I'm broke all the time because I don't have a job since I'm on the golf course everyday, but on the other hand ive been asked by several girls if they could ride in my jeep and I love every bit of it

35's pushed by 4.10 gears and 14-16mpg
tuned for 87 using superchip.

mileage saver XS doesn't really do much for me

Going to fab a splash guard for my CAI i'm putting back in when the weather breaks again

I have 35's with the stock Rubicon gearing. My computer readout will jump all over the place from 9mpg to 12.5mpg, so I don't really know where my actual mileage is at. I'll have to do the math from a full tank of gas I guess. I got a lot of weight with bumpers and a winch, but also have a roof rack, so I'm not expecting great mileage, but I get the feeling that my mileage is better than what the computer reads...seems like it anyways. Not complaining though, otherwise I would have not bought a big lifted Jeep. I just accept that it's all part of owning an armored vehicle...well it's pretty much like driving a tank around town. I love it!! Just the other day I noticed my rear Rugged Ridge XHD bumper had some blue paint on it from another vehicle. All I could think of was whoever hit me is going to have a big nasty dent on their vehicle. That'll teach 'em for getting too close.

jeeeep

2010 4dr, 35's, 4.88's, CAI, Performance Distributor, SC 91 tune - tested 93 tune since that's the premium here, got better performance not as good mpg, running out this tank of 93/ 87 mix and will test 87 tune

16mpg around town - use the cruise control as much as possible, Freeway 21- cruise control 60-65mph, 19.5 at 75mph

just got back from long trip, best tank 21.5 mpg @ 70mph, worst - strong head wind 13 @ 75mph. overall avg on trip 18.4mpg - all mileage/gas recorded and hand calculated.

I have 35s with 4.10 gears on a 6 speed and I get about 16 mpg average (hand calculated). 85% of that is city driving and 15% is highway at 80 mph.
