Can I run a 15 inch wheel on my Rubicon? Not stock wheel but aftermarket. I am not sure I have heard yes and no. Let me know. Thank You.

 

you have to get at least a 4.5" back spaceing. some still require a little grinding of the caliper. it's a crap shoot. i'm getting 15's for on my "X". but i'm doing a 3.75" back spaceing. hope this helps. this is a on going battle on the forum. some have to grind and some don't.

I am running a 15" rim on mine with a 3.75" backspacing and 1.5" wheel spacers. I have not ran it without the wheel spacers though. Here are some pics.

 

You have to worry about your brakes!

 

I'm running 15" MB razor wheels. National tire test fitting them. Need to be careful where the tape on weights go, but they fit without issue.

You need to have them test fitted just to make sure
