Will Rubicon wheels fit on my 97 XJ?

We have 3 cherokees, a 94 Yj and my 03 Rubicon in our family, friend has a 99 tj, 00 sahara, and 97 XJ.
My rubicon MOAB 16" rims went to my sons 95 Xj after a 3" lift, but he had tested them before and they fit, but if you 'stuffed' a tire or really cranked it-yes, the 31" MTR's were wide enough to hit the fenders.
For street driving, yes, they'll fit. For wheeling, no...first time you stuff them you'll know it.
Now they are on the 97 XJ, he just put in a 3" lift and loves them.
I'm running black steel 15 x 8 rims with 33" x 12.5" MTR's on the rubicon, my son has the same setup on his 95 Xj but he installed a 6" Xtreme longarm and hasn't stuffed a tire yet.
Don't waste your time with the aluminum rims for off road wheeling. There is a tremendous weight difference-the aluminum rims have to be 4 times thicker to handle the same load as steel, and they DON'T take rock rash very wheel. You can get 15" steel rims, 3.5" backspacing for less than $50 each and beat them to death.
Now, why are 16" tires more expensive than 15" in the same size (like 31", 33", etc.?) Simple law of supply and demand. The tires the companies sell the MOST of, will be cheaper, every time. The more you sell, the more you make, the cheaper it is to make them. Switching from 16" to 15" rims was weird at first-felt like the wrangler was 'swaying' back and forth-increased sidewall flex because of the increased radius of the sidewall. But once you get into some rocks-you can FEEL that tire flex and grab and you'll know why you went back to 15's. Especially with 12.5" width on 8" rim...wow, it's a whole new way to grab rocks and go over them! And I've hit 70-75 on the highway with them. But MTR's are too noisy to do that alot.
