Also, if you cut the rear fender to allow bigger tires, there isn't a lot of room left to mount a flare to. Maybe an inch between the cut and the door seem. That is why the plastic flare get mounted to the rear doors. And why the rear tube flares come attatched to fenders. Without fenders, you would probably end up having to weld the flare to the body.
When I bought my XJ in August, it had 30" BFG's on it with a 2" BB. The tires still rubbed. Not bad, but bad enough. So I cut. I was planning on going bigger on the tires anyway. I used rear TJ flares all around and trimmed the flares to match the body line. I will be going to the Hooligan style flares at some point, but for now, the TJ flares work well and look good. I like them much better than Bushwackers for looks and longevity.
