Who did you guys get to mount your 37s on the stock wheels?
Had the dealer install the tires on the rims. They also installed the Mopar lift as well. I added spydertrak wheel spacers to kick the wheels out for a nicer stance.

I have a Rubicon, no lift yet, but I am thinking of putting bigger tires on the stock wheels for winter and wheeling. With no lift, I assume a 37" tire would rub like crazy? Should I stick with a 35"?

In case anyone is still wondering. I just installed a 37X13.5X17 Discoverer STT Pros on my stock JLUR on stock wheels and stock suspension with no lift and they work fine for daily driving. All i did was install wheels spacers and they work fine no rubbing on full turns. I have to say though that i have not gone off road, but i think for light off roading it will work. it really looks good and im liking the low profile aggressive stance. i have ordered a lift but im thinking of running the way it is setup first and see how it works before installing the lift.

I just installed a 37 X 13.5 X 17 on my JLUR and it works, on stock wheels and stock height.

Installed Rough Country's tire relocation bracket. It will fit a 37" just fine they just advise against it in worry its too much weight for the tailgate. With the changes to the tailgate it seems fine. Eventually I will either reinforce it or go with a whole new assembly but for now daily driving its fine.
i plan on deleting the tire carrier all together, save weight and improve gas mileage a little bit. also like the look of no spare tire.

Blacked out my rubicon rims to change the look up. 37s with Mopar lift
Curious to know I have 37x12.5 on the factory wheels JLUR with the spidertrax spacers. What pressure did you end up with and how is the wear? I was told because of the small rim width I would wear the middle out quickly.

37" KO2 tires on stock Rubicon Wheels with Spidertrax WHS024 1-3/4" Wheel Spacers plus the 2" Mopar Lift. No Rubbing, full turn.
Did you upgrade anything on this setup, besides what you've listed? Looks great, but I see tons of posts about upgrading axles and all that when putting 37s on these...

Just what I have listed there. The axles on the new JL Rubicons are a lot stronger than the JK. I will eventual upgrade the shafts, but its fine for now.

I did the chalk test and running them at 29 psi and getting even wear.

Just finished my install of 37's on Factory wheels with a TF1.5" lift on my 2 door. Still needs a few things before I go testing the Flex but it runs great on road, lock to lock with no wheel spacers. Took it down a couple back roads on the way to work this morning handled great at 30PSI. I Still need to chalk test the tires and dial in the pressure, feels a little firm on bumps On a Side note the Balancer at the Shop that I had the tires installed failed on first tire so no weights were installed and ZERO vibrations got it up to 70mph so far.(most highways in PA top out at 55/65) The spare did not fit on stock carrier but I'm going to try to take a little air out, it barely overlapped.

Looks awesome. I really liked the factory wheels with no spacers. I had 37s on mine.

What size wheel spacers are you using?

Wow that's a really wide tire for a narrow wheel they can work yes but it ain't safe but I'm not going to argue with you that's my opinion and BrandsMart that are the tire business for a long time many many years won't even know something like that . And reason why they had people have the tire come off the wheel and disaster has happened you can run it probably be okay but there's been people that happen and that's why I love your tire stores disaster ha attire that why don't we all that narrow there's a reason they won't do it it's not because they don't want your business there's a reason because things have happened that wasn't good in the situation so they won't do it again. Like I said you may be fine but there's been people not over the years and it's just not recommended even though Tire manufacturers will tell you that's not recommended .there's a reason they have a wheel size for their tires when you're looking at tires on there sizing charts all chiropractors will tell you that's not safe to do like I said you can do it it's your get your vehicle to drive and something may never happen and you may be okay. But others have not
