Also, did y’all regear or stick with 4.10?

Still 4.10's here. I tend to drive in the mid to high 80's on road trips. Lower gears would only hurt fuel economy at speed. Our 4.7-1 1st gear is plenty low enough for crawling and hard take offs from lights/stop signs if so inclined.Also, did y’all regear or stick with 4.10?
Do you have a lift? What's your experience with your tires so far? I'm in an '18 JLUR 6-spd and my stock BFGs are getting close to the indicator marker. I'm 95% going to go with BFG 37s on the stock wheels with no lift until I get the Mopar lift (no crawling here).Still 4.10's here. I tend to drive in the mid to high 80's on road trips.

2.5" lift spacer kit with extended bump stops. The rear tires rubbed the lower portion of the fender liner at the small hump, removed the piece at the bumper and trimmed the hump off. We've had probably a dozen wheeling trips and 15k miles on the 37's without an issue. I rotate all 5 every 3-5k miles and they are wearing evenly and likely have another 15-20k miles left in them. 30-40k miles out of a very aggressive MT is not bad in my opinion. We will likely go to 40's when these are worn out.Do you have a lift? What's your experience with your tires so far?

I have an 18 JLUR 6 speed. About 20k miles on 37" KO2s. No lift but I do have 1.5" wheel spacers. I run 25 to 28 psi and it drives and handles great, no complaints.Do you have a lift?

I find 30psi+ on my KO2s make them wander at speed. Every tire is a bit different, good to know you can run those pressures on YokosI run 28psi generally, but if i'm making a long haul, I will bump it up to 32psi for better mpg and 8th speed on my stock gears.

Thanks for the replies!What air pressure are you guys running with 37’s on stock Rubicon rims? Specifically need to know for 37x12.5 Bfg ko2’s.
My tread looks a bit rounded due to the slightly narrow stock rim at 37psi.
I heard about a chalk test but don’t really know how to do it.
Thanks for any tips.
Question about your wheel spacers: did you have to trim the studs to fit the spacers?I run 37s with a 4.5in lift with 1.25in spacers on the stock JLUR wheels. My tires are Toyo M/T with 40 psi. Have not regeared. No issues. Runs smoother, quicker than my JKU did with 35s, 3.5in lift, 1.25in spacers with a psi of 35 that was regeared to 4.56. l am very pleased.
Just a follow-up to my earlier posts and questions :Thanks for the replies!
Anyone else?
I came back from the dealership at highway speed on 37” BFG Ko2s (set at 37 psi) and frankly I thought it drove better than on the 35 inch KO2s at same pressure :/
But I do notice some crown on the 37s which is why I’m concerned.
I run 26-ish psi on street with my 37" KO2s no problem and 14 on the trail without issue. But I wheel with a wife and 3 kids so I'm driving conservatively and definitely not using excess throttleJust a follow-up to my earlier posts and questions :
I am now running 28 psi (and considering dropping to 26) for daily driving with 37 bfg’s on stock Rubicon rims and a 2 inch lift. Rides and runs great.
I’ve been airing down to 18 psi for my off roading but I’m considering dropping to 16psi for a trip to Moab this weekend !!!
I’d like to know if I can air down even further??? No bead locks so a bit nervous to go lower than 16…
I usually air down to 15 on 37” Yokohama x-mt’s and have been known to hit freeway speeds in the dirt. Low speeds in the rocks where they are pushing against the sidewalls are the only place I’ve ever lost a bead in 25 years and that was running 10psi or less.Just a follow-up to my earlier posts and questions :
