I hate to ask again.... 35s and Rubi Rails

So I thought for sure this question had been asked a million times, but I could only seem to find one thread that mentioned it. I put on some rubicon rails over the weekend, for the extra armor and the good look. I remember when I put on my OME 2 1/2" lift looking at the back pinch seam and saying "hmmm, that looks sharp, I bet a tire wont like that". The rubi rail seems to line up with that perfectly. So I guess my question is, when I look to snag some new tires (i had been looking at a 33/34, but after some wheeling I want 35s) will new tires fit with no issues? My plan for now is some 315/75/16s, and if need be snag some wheel spacers too just to get em out even further. For extra info, its a 2011 jku, lift is the old man emu "budget boost" with between 2-3 inchs of lift. I'd be getting most likely and 16x8 or 16x8.5s, with the 4.5 back spacing. I really dont want to have to trim the seam or the rails. Well the seam I don't mind, but the rails look too nice, and I don't have the equipment to do it.

So the million dollar question, will it fit? And not just fit, but be wheelable?

be prepared to cut. Our 35s measure 34.25 and we need to trim them.

Is there a magic number to hit to avoid cutting? (In terms of tire size)

I would make a few small cuts on the rubi rails and get the 35's why go smaller if you don't have to?

mostly lazyness Hell, I'm considering just spraying rust reformer right onto the rails instead of just taking everything off and sanding and painting. cuz I'm just that lazy!

what size lift and backspacing do you have?

You can increase the rear bumpstops if you want. That would lessen the tire stuff at compression and keep the tire away from the rock rail end. Pretty much any tire size increase is going to put you on the rail if you do not cut it.

very sadface. is there an easy way to cut it? even the pinch seam seems a bit thick for tin snips. I guess I could find a good blade for a table saw, but I'm not keen on the idea of cutting that thick steel of the rubi rail without some proper machinery. or at least a water bottle....

the missus probably wont let me get new tires till spring, stupid me telling her thinner tires are better in the winter. oh well. means march i will be at your door, begging to destroy some perfectly good rubi rails!

that being said, feel free ya'll to keep chipping in on what size tire you could stuff in with a rubi rail and if you have to chop off part of it or not

No pics that I can find. Simple enough to check. Place a straight edge along the tire to the ground. From it's widest spot. See how close you get to the unaltered rock rail. 35's are very close. 37's require the chop. But the straight edge will show you the path of the tire at stuff. It is remedied with extended bumpstops, but you lose the stuff as well.

Heres a few pics of mine, with the stock 32 sras. It seems alot of the "does it need to be chopped" might be tied to "will it be offroaded" it looks like a gap of not too many inches. But I suppose back here in the real world, I could just buy the damn tires, stuff them in there, and if they dont fit bust out the chainsaw. just hoping for some advice from others in a similar situation

Buy an angle grinder from Harbor Freight for about $25 and a can of flat black Rustoleum. Spend an afternoon enjoying working on the Jeep. Oh, don't forget the beer.

Here's mine. 37" MTRs. 3.5" Rubicon Express lift. Added a hoop and a few spreaders to the rubi rock rail (after the chop). Also note. The rock rail and the tub pinch seam were cut. The pinch seam is what will cut the tires.

heh, that 37 looks wicked tight with a 3.5 inch lift, i cant imagine going higher than that. although maybe a 3.5 with 35s will fit without the need to chop. or I could just cut the pinch seam and ignore the rubbing from the rubis.......

4" and greater will require new drivesahfts on the JK. Didn't want to add that cost at the time. Cutting on it did not bother me. Just did a snorkel a couple of weeks ago.

You only need to cut 1.25-1.5-inches to clear. Remember your axle travels in an arc, no up and down. There is only one point in the travel where it is an issue. If you cut it straight, you can reuse the end cap and it will look untouched.

My rock krawler 3.5 lift actually moved the rear axle back 1 inch. Doesn't hit the rail or pinch weld. Rubs the stock bumper and wheel flare tho
