Please list MPG over total miles, percentage spent on highway/city/offroad, size of tires and if you’ve calibrated your speedometer for the tire size

I’m at 13.3 MPG over first 1000 miles
60% highway/40% city/0% Offroad
On 37s and calibrated for 37s

I’m at 13.1 MPG at 950 miles in. That’s about 15% Highway, 84% city, and 1% off-road.
35” Nittos, calibrated with tazer to 35”.

I’m heading out to some forest service roads and a few trails tomorrow. I’ll reset the average and let you know how it does for the day.

14.4 with 1800 miles. Lots of highway miles unfortunately. The rig doesn’t like wind and it’s hard not to make the loud noises at stoplights. Sitting on 35x12.50 and speedo calibrated. The tires seemed to have hurt it some.
I may baby this tank of fuel and see how well I can do.

Do the 392’s not have the 4cyl (MDS) and Eco mode? Or is this WITH those selected?

They are in sport mode and hammering it LOL
My SRT has avg a tad over 20 mpg and on highway grandma driving style doing 65-70 will pull 27 mpg on long trips.

do these 392's have any modes, to change the steering and trans? on my SRT you can tune the suspension( adaptable Bilsteins), steering (tighten up the feel) and Trans ( shift points and shift speed), have street, sport , track modes.

Only selectable mode is exhaust.
Shaped like a brick, pushing 33-37” tires with heavy Beadlock wheels.

Dont mention steering in wrangler forum.
Tightness of steering on a Wrangler depends on wind direction and road curvature .
