I couldn't resist...complaining about MPG is like eating bacon and saying it's too greasy: "get a hold of yourself man!"
But yeah, you're right.

|DallasJKU||I get 14-15 mpg on 35's. I get the same mileage on the highway also. The faster you go on bigger tires in a Jeep, the more your mileage will suffer.|

At 4$ gal.
The fuel cost over a year (US average gallons used) would be roughly $400 more for a JK than a 30 mpg average vehicle.
That's 33$ a month.
Figure your own average cost and do comparison for yourself.
That gives you a clear picture of the economic trade-off.
FWIW, I'm getting closer to 20 as I break in (now 18.2 with 1200 miles).
Not bad at all considering other factors.

|pepatrick||I feel like I am ahead of the game with the Jeep. The last 7 years I had a 2006 F-150 and 2011 Chevy Avalanche. These got a whopping 15mpg. The Jeep gets 17.7 avg. no matter how I drive. I didn't buy it as an economical mode of transportation. I bought because its a Jeep. I don't like the high gas prices as much as anyone else, but I knew gas prices were high and Jeeps get crappy gas mileage when I made the decision to buy one.|

|ohioviper||Say what you want I have owned Jeeps for the past 25 years and I know the mpg suck. But.... when gas hit almost $4 a gallon here in Ohio the past few weeks it suddenly becomes an issue that gets your attention when its also your DD.|

There's too many threads in here about MPG...if that is such a big issue for some, wouldn't you do your research about it before getting a Jeep or getting a lift or those wheels or tires? I don't get it. Even if one doesn't have any concept of aerodynamics, look at the shape of it. And the weight. What were you expecting? Then you lift it and put bigger/heavier wheels/tires (ie. unsprung weight)
It's one facet of many and considering all of the positive facets it has (ie. go ANYWHERE, doors off, top off, a vehicle one enjoys driving, etc), who cares if MPG sucks?!? Is that why you bought it??? No? Then stop complaining about it.
Rant over seriously though, Jeeps do so many good things, good things that are way better than other vehicles. If MPG offsets all those good things, sell it and get a subcompact...oh but wait, you'll probably end up complaining about how it can't crawl rocks. Can't win.

I have a 13 JKU auto that had 3.21's. When I put a 2.5 lift, front and rear bumpers, winch, and 285/70/17 DT's my milage went down maybe 3 mpg. When I regeared to 4.10's I got most of that back.
I hated the 3.21's and it was the best thing I did. Now my JKU will actually stay in 5th gear.
|06-19-2013 12:28 AM|
|terrabit||Maybe, but 35s are bigger and they look nicer.|
|06-18-2013 10:10 PM|
|ohioviper||3:21 on 33" and under tires will net the best mpg you can get .|
|06-18-2013 10:10 PM|
|dawhitesJKU||I'll regear in the future once I add significant weight. But I'm never going 35's. past experience cost me 1k on gas monthly.|

|dawhitesJKU||^thats the only reason y I love my 3.21|
|06-18-2013 09:57 PM|
|ohioviper||3:21 gears do help with mpg.|

13' JKUR auto 3.73 with 2.5" TF coil lift and 35/12.5/17 Toyo OC MTs getting 14mpg in the city (manually calculated at the pump). Haven't tried it on the highway yet.
These tires weigh in at 82lbs each.
|06-18-2013 09:24 PM|
|dawhitesJKU||^thanks to the lightweight duratracs. Nice mpg #s|
|06-18-2013 09:20 PM|
|ohioviper||33" DT 2.5 TF procal adjusted for tire size. I averaged 20 mpg to Bantam with wind behind me. 17 mpg on way home into the wind.|
|06-18-2013 09:16 PM|
^35x12.5/16 measures 35.03 tall/ 12.52 wide.
315x75/16 is 34.6/ 12.4 wide.
|06-18-2013 09:02 PM|
|06-18-2013 04:54 PM|
^they differ from their actual measurements.most if not all will measure slightly less from manufacturer specs. I measured mine when mounted and adjusted procal accordingly. Not by what numbers were given from tire manufacturer.
also, 315/75/16 are considered 34, but many consider them 35's. same goes for the 315/70/17
|06-18-2013 04:13 PM|
I know you mentioned recalibrating, but did you do it by programming it for 33 inch tires, or did you actually measure the tire while sitting on level ground? The Duratracs run small, I put on 315/75/16 Duratracs and they measure 33.75 inches, far from 35 inch tires. I'd try a remeasure and reprogram the Procal again and then run it a bit.
Aside from driving into the wind here (usually on I35 south), I have been averaging 17 mpg with mostly highway driving now. It does drop a lot if I do city driving though. If I work in the Jeep one night and drive at idle-15mph for 8 hours, I average 8-11mpg.

|dawhitesJKU||mid 19's low 20's on 285/70/17.|

|jeepjungle||That ticking could be a manifold leak. Some times a bolt brakes off and starts leaking air it makes a ticking noise.|
|07-12-2012 12:29 PM|
|Doug4823||Thats what I thought. Definitely been enjoying it but I've intentionally taken it easy on the last two tanks with no improvement which weird. It misfired last week and blew a spark plug and started ticking which the dealer fixed. The ticking still seems to be there though? Could that be it?|
