The 32's on the Rubi are not an 11.50 but will a 32x11.50 fit with no lift? This is what I am considering for my new X unlimited. I was thinking a 265/75 R16, which is a 31.6" x 10.40? One more question, will that fit on the X aluminum wheels= 16x7?

 

The stock tires actually measure 32.1x10 and I can tell you for a fact that in the rear, you only have 1-3/8" between the sidewalls and the rear sway bar. Also, up front, at a full lock, your tires will only have 1/2" between it and the plastic air dam. So, anything you get can't be more than about an inch wider without new wheels with less back spacing or wheel spacer and you can't go any taller without a lift or doing some trimming.

 

Those are only .40 wider and .50 shorter.
