Regarding fuel economy if we can call it that, I recently had a roadtrip with approx 40% city, 40% country road and 20% offroad and had an average mpg of 19.5mpg

Just came back from another road trip with 10% city and 90% country roads, no wheeling and my average mpg was 23.5mpg.

Thats with 315/70 and 4.56 gearing it never ever hunts for gears mow and I am totally satisfied. I would still recommend going to 4.88 if you think 37’’ tires are in your futur with this Jeep.

That sounds pretty good, the MPGs. Pretty much stock numbers. People keep saying I'll want 37s later on but I highly doubt it. I'm definitely leaning towards 4.56 with my lift and the 35s.

Listen to the people, they speak the truth :)
I thought 33s were fine, I now have 35s in my shed waiting to be installed. IMO a 2dr w/ 35s is similar on the trail to a 4dr w/ 37s, so I'd imagine 37s will eventually be on your radar as that seems like the true sweet spot w/ 4drs. But???

Yeah personally, I think the JLU with a 1.5 to 2 inch lift looks great and balanced with 35s.

Considering the added stress of 37s, I know I’m not interested in going any bigger.

I took a minute to consider the conversations that happened in this thread—especially the ones where I participated, and I went back and deleted all my posts. Frankly, because I allowed my temper to cloud my better judgment and I posted a few things that I should not have in the way that I did and for that I apologize to the OP and anyone who took offense.

At some point in the thread, it was stated that we should allow people to be wrong. I disagree and this has nothing to do with whoever posted it nor is this intended to start another chain of discussion--this is my opinion, ignore it and me if you disagree.

So why should we not allow someone to be wrong on a forum? Seems like it is the easy button and would prevent a lot of bickering and drama. No harm, no foul, right?

Not exactly. With rare exception, people join the forum and make posts seeking advice (I am definitely in that club and have done it on countless occasions). Be it for a potential solution or an upgrade, they are seeking advice. With that advice comes a level of trust since many people on any forum have experience or expertise in a field or fields and the poster is looking to leverage that expertise.

Also with rare exception, that advice translates into a decision. That decision then translates into a financial transaction, ergo, if bad advice, then bad decision, and ultimately money spent in a bad way. Oh, but the OP should be able to figure out what is good versus bad advice and internet advice is worth the paper that it is written on, right? Maybe, but more likely maybe not—remember there is an assumed level of trust in that advice since this a forum dedicated to all things Jeep JL and since they were here seeking advice it typically means they do not have the answer to the question(s) they are asking.

Everyone single one of us on a forum like this should be calling out bad advice when they see it. Although it may create drama, it makes the technical information sounder and strengthens the validity of the forum as a whole—but it should done in a good way and backed with objective and repeatable data. It is difficult at best to defend anecdotal information and sometimes that is all there is, but when it is wrong, it is not fair to the person asking for advice for that information to go unchecked. I would expect each of you to call me out when I post bad advice, but back it up with data that is objective and can be used for me and others to learn from my misinformation.

In the end, I am certain all of us are here to learn and share—just remember the trust factor that is inherent in all of the advice that is given and do your part to ensure the advice is sound and call it out when it is not.



OP – good luck with the re-gear.

Great Post, but you should have kept your posts in the thread as they were valuable!

You make a lot of good points. Being new to the forum I figured it was a good place to ask questions and get advice. Obviously whatever advice I do get is up to me to decide what's best for me and do my own research outside of this forum. Arguments happen, especially on the internet. I appreciate all the advice from all sides. I do believe I have my answer and decision on the original question. So in the end the forum works as it's intended. Thanks for all the information!

Hey, sorry to cut into this thread, but this looks like a conversation I might benefit from?

So newb question here, I'm gonna order a JLUR tomorrow, with a manual transmission. For options I have the 4.10 or the 4.88 (no XR package for manual sadly). I plan to put on 35s right off the bat. I've gotten mixed advice on what I should pick for gearing, and I've had people tell me that because I'm getting a manual that changes factors and I should stick with the 4.10 . I've had some people tell me to for sure go for the 4.88s.... Anyone willing to offer some advice?

If I should post elsewhere, let me know and I'll delete and go where I'm pointed instead.

The manual needs gearing sooner than the manual. Order the 4.88s, they will be perfect with 35s.

4.10s are unsuitable for 35s. Some recommend 4.56, some recommend 4.88. Either way, with 4.10 you'll have to pay to regear. With 4.88 it's very very unlikely you'll want to regear to 4.56. (Even if you did, you would have had to regear with 4.10 anyway). It's a no brainer and the least risk to order 4.88.

If you're never going to go off road, get the 4.10s.

If you're going to go off road, get the 4.88s.

The 3.6 with manual transmission will benefit from 4.88 more than any other JL combination.
