37’s on stock Xtreme Recon

jandersendo · Mar 20, 2022

I know they’re a lot of threads on 37 inch tires on stock high 392 and I see that the only issue with rubbing is on the lower control arms. With wheel spacers help this? Anyone with an XR run 37’s on stock height?

Following. The offset on the xr wheels would be like the non xr with spacers. The front bumpstops on the xr don't allow much up travel. Don't know about the rear. I think 37x12.5 would probably be fine on streef but would be interested in first hand reports

Correct, they fit fine for street. My buddy has them and no issues whatsoever. I am no debating to keep the 35's or go bigger but I kind of like the stock setup.

Is there any rub on full lock on the lower control arms? A video I saw they rubbed but that was on a non-XR

I am running 37x12.50 Goodrich KM3s on Hutchinson 17X8.50 wheels on a stock Rubicon 392 with no rubbing or bumping issues experienced so far.

What’s the offset of those wheels compared with factory?

About one inch from factory

So 1” wheel spacers on the factory wheels should do the trick?

I'm not sure about that. Hutchison Wheels seem to have the correct offest built in for JLs and JKs.

Do you know what the offset is of your wheels?

Nope, but I am sure the specs are available here somewhere... rock-monster-internal-double-beadlock-system

I would go with 1.75" spacers. You shouldnt have to modify the lugs that way and it will put you about where you want to be.
0 or -12mm offset wheels would be about right. I believe the stock are +44? 44mm is about 1.75" ... so that spacer would put you at about 0 offset.

I have 35's and plan to stay there. I really love the stock wheels but wish the 392 had a wider stance. I also feel that 1.75 inch spacers might be too much. Not sure where I am going with that but I do know 1 inch spacers are a non starter.

I wonder is 1.5" would fit without messing with the studs. I think the XR wheels are +12 offset. 1" would be the sweet spot but 1.5" may work... maybe even 1.25 if the studs fit in the back of the wheel hub? Not sure what the back looks like.
This makes sense in my head .. although maybe it doesn't written down lol

I've really only seen 1.75 inch spacers for the JL so I assume that is what's required to clear the studs. The spacer has to be at least as thick as the studs are long.

Yeah.. Ive seen 1.5 and 1.25. Was curious if the studs could sit on the inside of the back of the wheel in the dead space.
Cant find an image of the back of a Mopar wheel

One review on Quadratec of 1.5 inch spacers say the stud sticks out .190" but that fit into the pocket of the wheel. I did not think that was possible but I can picture it now.
