Currently have 35” BFG KO2 on my JK with a 4.88 gear ratio... I want to go up to 37s on my next set of tires... who has 37”, what gear ratio you running, and how do you like it? what’s your MPG?

2010, 3.8L, 4 speed on 37s w/ 5.13s & the rubicrawler

Offroad it is great. On road it is fine. Could use more power at highway speeds on hill climbs & such but the 3.6+5 speed solves that

12-15 MPG city vs highway & depending on how fast highway.

At 70-76 we get around 14 mpg... worse the faster we go

Wouldn’t go back to 35s though for wheeling. 37s on the long wheel base is really the minimum.
