Just went from a JKU Ruby to this and wandering how they do with 35's and 3.73 gears. Six speed also. Thanks

 

I'm running 35's on my '14 Rubicon 2D Auto. The increase in tire size takes me from 4.10 to 3.74. I don't have any plans to regear.

My 35's are actually 34" in diameter when I measure them even thought they are 35x12.50-17. If yours are 35", you went from a 3.73 to a 3.30. If they are 34", you are now at 3.40.

I have a 2013 2 door, 6 speed, 35's, and 3.73 gears. I'll call it tolerable, but frustrating. Unless it is flat road with no wind, cruising in 6th is tough (unless you run closer to 80 mph, then you're at a better rpm). On a trip from MD to IN, I was doing the 6th-5th-back to 6th shift, about every 2-3 minutes. I literally had a sore hip for a week. The Olympics called the next day when they heard about my rowing skills!

For now, I think of my Jeep as a 5 speed and rarely use 6th. Not worth the hassle as I know I'll have to shift to 5th soon after. I think I'm around 2500 rpm in 5th at 70 mph.

 

Going with KM2's again and I believe my last set ran 34". Just wandering because my '07 JKU Ruby was OK with 4.10 and 35 but my 10' JKU with 3.21 was a turd. Had to regear to 4.88. It should be better with less weight and more power until I regear.
