This basically applies to new Rubi owners with the 3.6, but I'm looking for mpg numbers on anyone running 4:10 gears with 35's or 37's. I know my mpg's will go down with bigger tires but I want to know just how much. Truth is, I want 37's but not if I'm going to be getting really bad mpg's. The Jk is my daily driver and I do drive a lot on a daily basis and I just don't want to have to fill up every two days. Any help is appreciated.

 

I have a 2013 JKUR with an auto, 4.10's, and 37's. I am getting right around 15mpg. That being said I do about 50/50 street and highway driving. On a road trip I saw a best of about 18mpg.

 

2007 manual JKU 5.13s and a snorkel on 35s and 6" coils.

14.8 on highway over 6mph
~18mph driving around town nice a slow.

 

Park the jeep and get a prius

 

3.6 4.10 35 Duratracs got 16mpg at 70mph to the beach last week. I get around 18 at lower speeds.

EDIT

I should have added that I'm lifted with the RK 2.5 Max Travel and have steel bumpers front and back with a winch. The weight makes a big difference.

 

2013 jk, 35s, 4.10. 18 city and...

13 jkur auto 4.10 on 37". 17.5 on 2 lane hwy, 16 at 77 on interstate, about 15 in town with red lights.

13 JKUR Auto 4.10s 35s

17.5 around town and a solid 18 when I hit the highway for local trips but that's doing 80. I've seen as high as 20 on a couple longer trips when I kept it under 70

 

Im on 35 and I put about 20 $ a day in and do around 110miles a day granted my dash is telling me im getting 14 or so mpg but I trust it not
