I average 21-23 with mopar lift, 35x12.502r17 grapplers at 37psi in southern AZ with 50/50 driving.
Added weight includes:
Billie bars
Cargo rack
Bike rack
Arcus front bumper w/badlands winch
Jcw rear bumper
Access lowrider tonneau cover
JCR Chase Rack
LOD Destroyer rock sliders.
Rough Country molle panels

Towing my overland trailer in the mountains I get 15-18mpg at around 65-70 mph

You guys must live in flat land with low gravity and never drive uphill to get that kind of mileage. Bone stock, the best i ever got was 27 on a trip. Around town was 22. Now with the 37's. Close to 20 around town and maybe 24 on a trip.
My numbers are similar to your on 37s as well.

Sorry, but 3/4 of a tank left doesn’t count for mpg in these rigs. Show me that average with <50miles range left. I consistently can get 27-28mpg the first half of the tank then drops to 22-24mpg when I spent all but a 1/4 or less of a tank left. Unless you’re calculating it by hand of course. For the 7mi trip from Buccees to my house I can have that average at 38mpg but yeah that’s not the actual average over a tank of fuel.
Wasn’t averaging the whole tank the mileage on the freeway has gone up exceedingly since they replaced the turbo on my 21 my 23 only get 25mpg on stock wheels and tires freeway

I've been noticing wildly varying qualities of fuel lately. I drove from St. Louis to Dallas pulling a camper. I was seeing 17-19 cruising nice and easy, except for one tank that was showing 9-11 and Stanley was kinda grumpy.

That sucks. Mine was stolen using the same process. I was just fortunate enough to see it driving by and it was stopped at the border less than an hour later. Now its got quite a few additional protection measures. Hope your insurance took care of you

I hate to hear that. I actually have court tomorrow as a witness to mine. I happened to be out walking my brand new puppy and saw my Jeep drive by. It was the power of the internet that really helped mine because someone from the BP saw my post on instagram and recognized the Jeep as it was crossing into MX.

I was talking with police and sirus xm then they blocked me from the app but the officer said they had a picture of the plate crossing the border the story is unbelievable when I get some time I’ll put the whole story down people should know how easy it is to steal your jeep

I see 20-ish on 35s in flatlands, 60/40 highway/city. I've found I get better mpgs in mountains and hilly areas vs flats. Flatlands you are always applying throttle with next to no coasting, mountains and hills you're coasting often. Sure, you're applying more throttle to climb the hills, but I think it's less overall than consistent throttle in the flats.

4.5” lift and 37s I see 22-22.5 quite consistently with 23 on longer drives on the tank. When I was bone stock I’d see 28-29 consistently with 30 on longer drives on the tank. I was able to go over 500 miles per tank on multiple runs with the stock setup.

That's why living in the middle of nowhere has its advantages
