Did some highway driving today in my 2013 JKUR today. It's lifted 2.5" sitting on 35" MTR's with factory .410 gears driving 70-75mph and averaged 16.5mpg. Was pretty happy cause in town it's around 13mpg. What do you guys think? Good or bad?

16-17 is pretty decent number my 2.5 lifted with 37s averages about 14 around town 15.5 highway

I just had 33" A/T's put on and my mpg around town has dropped big time; getting around 14.5 mpg. On the highway it is still decent, but I haven't had the tires long enough to tell. All I know is that a regear will be in order soon. These 3.21's aren't cutting it.

I get 15 city and 18 highway. No lift with stock tires and wheels. I am not aggressive with the accelerator either. FML

16-17 with a 3 inch lift and 37s with stock 373 gears.

When you put the larger tires on did you adjust the speedometer?

Makes a big difference and only to get correct mileage.

2.5 lift and 35" Nitto trail M/T ,4:10,auto and Flashpaq = 16 MPG

2013 JKUR w.4:10s on 35"BFG KM2s Calibrated with AEV Procal.
Left here at 500 ft. elev. and climbed to over 7200 ft. in 120 miles. Played in the snow a bit and came back. 17.081 MPG doing the math. (I still don't trust that EVIC thing)

No complaints at all

I just had this conversation with a friend yesterday. We have similar setups, 37s, 4.88 gears, etc. I get 17.5 on the highway and he gets 14. After a quick discussion, we discovered the difference. When I hit the highway, I set the cruise at exactly 70 mph. He likes to cruise around 80. I've seen my mpg drop notably for every couple mph's over 70. The impact of drag is exponential. Stick to the speed limit and mpg goes up.
