I will cut mine as well. (see pics attached), but just out of curiosity, why would Jeep design it that way if its not needed!!!.So this morning here in beautiful, sunny Wisconsin we were having a white-out. 50-yard visibility, with 30 mph winds. Good day to put your head in the oven, or something. :thumb:
Instead of baking my cabeza, I decided to trim the pinch seams on my Jeep. Now, a lotta peeps think this is a must when running 35" or larger tires, but that's not necessarily the case. A lot of things factor into it: the size of your lift, the running size of your tires, whether or not your lift has adj ca's & tb's, etc.
Also, when you stuff your rear wheels, they generally go up, and slightly to the back, which moves them away from the cursed pinch seams. But again, this depends on your lift, tires, etc.
The pinch seam is most dangerous when you air down. Crossing an obstacle – a log, a rock, a trench – will bulge your aired-down tire. That's where many peeps run into trouble with the pinch seams.
Mine PROBABLY had enough clearance to not be a problem, but I keep looking at it, and thinking about it, and eventually decided that it had to go. Plus last night I dreamed about it slicing my tire on the freeway, and jerked awake to echoing laughter, so...
There's a thread on WF about the "bend" method of getting rid of the pinch seam, where you take a BFH and pound the crap out of it till it bends back and in. Seeing as how I'm no caveman, I decided on a more refined method.
Here it is, pretty much step-by-step.
*****WARNING: Some of the steps outlined here are anal, and can be avoided by those of you who are less concerned with quality, rather than results.*****
Here's what you need to do the job. Pretty much self-explanatory. Two things not in the photo that I used were safety glasses, and a putty knife for spreading the JB Weld.

The offending portion of the rear pinch seam, with painter's tape to guide my cut.

Close-up of the pinch seam. The plastic on mine is the tail end of some Bushwacker body armor. That's toast, too. If you run your fingers along the back side of the pinch seam, you'll feel a channel. If you cut into the channel, you'll expose a gap in the sheets of metal that will need to be filled with JB Weld and sanded before you rustproof and paint the cut edges of the seam. In my case, I didn't feel it was necessary to make that deep of a cut, though I still used some JB Weld. You'll see why in a few.

Post-surgery. Man, my hands are steady. Like stone. Make sure you don't goof around with the cut; start it, set the blade and let er rip. If you stop and start a bunch, or hesitate, you'll end up with a zig-zag. I don't think it took a full minute to lop the whole corner off.

Tight shot of the cut. Notice the separated strips of sheet metal. That's because, when you cut off the corner of the pinch seam, you're cutting off the end-most spot-weld that holds the various metal panels together. But fear not, there are welds all along the bottom of your pinch seam. The Jeep body won't come flying off next time you peg the speedometer on the freeway. Hopefully.
