Jeep pinch seams
Will be going to Palo Dura jeep jamboree this week and was wondering how important it would be to get my pinch seams cut? I have a rubicon with the rubi rails on it. I have read about how the seams can cut the tires and cause problems but did not know how often it would happen. I don't want to be out on the trails and have this problem. I have the bfg 35x12.5x15 in tires if that helps with a 2.5 lift.

It's not usually necessary with 35" tires unless you're running shorter rear control arms.

I thought(reading a ton in the forum) that 35s were the point u needed to cut the pinch seems. If I had 35s, I would.

I have roughly the same lift and tires and I cut my seams. I have a sport and picked up some Rubi rails on Craig's list and I cut them too.

35's are right at the point you should consider cutting your seams. For most wheeling there will be no problem because when the tires flex they will go up and slightly to the rear. I have heard the stories about people getting their tires slashed from the pinch seams but haven't seen it personally.:whistling:

When it all came down to it and I was looking at my rig after installing my lift and tires, I didn't like how close to my back tires the pinch seams looked. For me, it all came down to the comfort factor. ;)

Should the pinch seams absolutely be cut with 35" tires? Probably not, but I feel better rock crawling with them farther away from my tires. Besides, it's an easy mod and I'm all about easy.:thumb:

It seems with the rubi rails on there, that it would be hard for the pinch seams to cut the tires since the rails extend out just a touch farther then the seams. Just didn't want to get into a bad situation while out on the trails. Thanks to all for the input.

You should cut them. I have 35's and when flexed you will hit the rubi rails, which will keep it away from the pinch seam, but there will still be rubbing. When you get near stuff you will also push on your stock fenders as well.

I have a 2.5Ē lift, BGF 35s, and Rubi rails. I didnít trim my rails and pinch seams until I heard them rub. If youíre going just the right speed over just the right kind of bump the wheels rub on the plastic tab on the end of rails. For me it didnít happen a lot because they didnít rub when I was crawling over stuff, and didnít rub when on flat surfaces.

I ended up cutting the rail and bending the pinch seam because it got to be annoying.

Looks like I will be getting them cut before I go this Wednesday. Not gonna leave me a lot of time to do it.

35's usually don't need the pinch seam cut but it is getting close at that point. I did mine just to be on the safe side but was told by the shop I didn't need to but did it anyways. Would never want to say not to then have to deal with someone getting their tire cut and coming back and saying, I thought you said it would be alright especially when I did it myself lol

Depends on your 35 and how close to an actual 35 they are. My MTR's needed the seams and rails cut.

I have 35" Duratracs with a leveling kit and it was way too close. I would hit the rails whenever I went up driveways or over train tracks

Im with Matador on this... my 35s came SOOOO close to touching. Def cut, its not hard at all. just try not to cut your face off in the process... right Matador?

After installing the 2.5 inch lift and 35s, I cut both the pinch seam and the rubi rails. I just didn't like it that close.

Getting done tomorrow.

"Getting it done?" As in, paying for it?

Save the money: Cutting your pinch seam

BTW...I agree with post #2 above. For 35s it's a case-by-case basis, depending on your lift. I cut mine solely on paranoia.

35" Duratracs on mine with a 2.5" RockKrawler Maxtravel lift. Cutting is required. And to be honest I still need to cut mine even more since the initial amount was not enough....

Even after cutting I still hit when off road so looking to recut more dramatically, something along the lines of this image. There's merit in the idea of using the plastic end caps as a buffer rather than letting the tire touch the pinch seams.
