i just got a set of 4 TJ rears for my xj. they are wider...but not by a whole lot. they do look a lot wider thought due to the fact that they are more square...and dont slant down towards the tire. does that make sense? I only need about a half of and inch or so to cover my tires, and it looks like these flare will do it. plus i think they look much better than the original flares on my 94... i know that doesnt really help you much... just my $.02.
