nice link, jahbone
I trimmed my seam at about the same angle as Mopar did on later 13s. That is a good line.
I also had a little bit of space between the sheet metal folds and put some rtv in there and touch up paint. Never have to worry about it again with 35s or 37s.

I have the same question so I didn't want to start a new thread. What do you think?

I am running 35" Duratracs with a 2.5" RC lift and factory control arms. I have maybe 1/2" clearance to the pinch seam at ride height. Is it save to assume that the control arm moves the tire backwards when it flexes up? If that's the case do I have to keep an eye rather on the rear bumper than the pinch seam?

I've yet to see a 35 hit the pinch seam but it gets extremely close and slightly will rub factory rock rails.

If you cut yours I recommend filling the body gap with something more substantial than the foam in it. I used 3m 5200 Marine sealant/adhesive. It's not cheap but you don't need much and it will permanently seal the hole.

This pre-owned Wrangler came with Smittybilt Side Steps instead of the factory rock rails. So I guess I don't have to worry about this section at all. But what about the rear bumper? It blends into the factory fender flares and looks pretty close to the tire already. Is this going to be an issue if the control arm moves the tire back?

I see some Buschwacker flat fender flares in my future and if the bumper might rub I would cut it so that it follows the line of the flat fender. I just don't want to find out if it rubs on the trail.

I have a 2013 that was just built this month and the pinch seam is trimmed from the factory. Good job Jeep. I think I need to trim the rock rail though.

This pic is my 35s. When they are stuffed to the max they do hit the bumper and fender a bit. Hasn't done damage to either though. (I have the 3" teraflex rear bump stops and factory control arms)

When I put 37s on my 12 jkru I had to not only trim my pinch seam to the wheel well but also cut about 3" off the stock rock slider hopefully helps ya out
