Quick gear question/rationale
I have a quick gear question and break down of what my rationale is. Let me know what you all think in regards to what gears I should run.
Jeep Info:
- '13 JKU and looking at running 315/70R17 Nitto Trail Grapplers on. As most know the Nittos are heavier.
- I don't see myself running 37s anytime soon. However, if I run the Nitto Trails in 35 or 315/70 they are a heavier tire as mentioned.
- As far as weight, I hope to get a front and rear bumper and winch sometime in the, hopefully, not too distant future. I currently have the Rubi rail and Ace sliders.
- my JKU currently has the 3:73's
- terrain around here isn't mountainous or very hilly. More mud than anything.
Rationale:
I had 4:56 in my Tahoe with 6" lift and 35s years ago along with a programmer and it seemed to do alright. Although the jeep is going to have less horsepower (don't know that that matters much). I'm thinking that I would not really be able to tell the difference between 4:56 and 4:88 as far as daily driving goes, mpg, etc., etc. So that makes me think that maybe I should just go the 4:88 route. My only hold back of just going 4:88 is due to the fact that my rig sees mostly pavement and a good mix of highway/city, maybe more highway than some. I have to drive interstate everyday for work. Not long distance though.
Are my comments on not being able to really know the difference between the 4:56 and 4:88 sound about right? OR is my normal day to day driving habits sound like I need to stick with 4:56?
Thanks.

We are almost the same except I have 4.56's and I geared it for 37's.... soon.
For 35's in the Nitto's I recommend 4.10's as an all around gear.
But for off road and in town driving the 4.56's can not be beat.
RPM is a little high on the interstate but not so I care.

However, 4.88s will be better off road, and the mpg should be better for in town mpg.
Unless your daily commute is long at 75-80 mph, 4.56s don't make any sense. (They cost more than 4.88s.)
Do you have a long daily commute at over 75 mph?
Does less than 200 extra rpm bother you?

I'm running 315 duratracs which measure out to 33.75"
I'm running 4:56 gears with a manual Trans.
It's my DD and toy.
I think the 4:56's are the perfect gear for my setup.
I can start off in first without giving it gas, but it's also manageable at 70 mph.
I'm getting the same mpg I got with 32's and 3:73's
