Gears and Tires

JK Super Freak
If you're doing 35's with an Unlimited model, or either one with an automatic trans, I'd definitely be looking at 4:10's or higher. I did some reading and I think someone recommended 4.88's as a middle ground for having good crawl-ability but still being (somewhat) efficient to drive on-road.
That's just IMO, anyway...

Just re geared last week from 3.21s to 4.10s on a 2012 auto with 35KM2s.
Finished my break in 1 hr ago so I will be able to tell you soon how it is on the hwy. around town I got my power back and now at 16.3 mpg vs the 14 I was getting with 3.21s.
Excited to get on the hwy Friday and head to Jeep beach!

4:10 or higher, in my experience. I've got a 6-speed manual 3.6 JK on 33's with the stock 3.73 gearing and it feels just a little sluggish on-road.

I have 4.56 2012 6speed and it's great I don't think I would've went with 4.88s would've been too much rpm for the amount of highway driving I do. I could not be happier with my 4.56
