Good lord, what a bunch of "don't do its" first of all XJs are old cars, "forever" to an xj could be 2-3 years.
XJs are not a keep forever vehicle.
Is the point of bigger tires to look cool? Or wheel better?
Sorry trick question, A and B are correct. I have a 95 XJ with many wheeling miles on it, it takes one hell of a beating and keeps on going. 35" MTZs, 4.5" lift, 9" detroit rear, OED30 front with ARB, 4.10gears, sliders, cage and frame supports. and most of all dents and smashes (battle scars) the body is cut to fit the tires and yes they still rub a bit, and NO the seams where I cut it don't create a problem where the uni falls apart? (that is pure funny) and no where I cut the inner fanders on the front does not create an opening to throw mud inside.
Cut it, use it, beat it, wheel the crap out of it, buy a new one when it is trashed, or just step up to a TJ with a real frame. But whatever you do don't listen to folks who don't know anything about your rig. Go to NAXJA.com to learn about XJs
