Backspacing???

I would have expected them to say 4.0 or more. I started almost the same as you on my 2014 JKU and had a tiny bit of rub with 4.5 backspacing and factory fenders with MTR tires. Might be different on a JK though. I also added I think 1 inch increased bump stop in the front and 1.5 in the rear.

I eventually went to 37x12.5 with metalcloak fenders, added a bit more bump stop up front and still rub a tiny bit when flexed.

I decided to do a big brake kit with the factory caliper spacers and wished I would have done 4.75 backspacing so I could do the larger rotors, the Teraflex kit works well but there was another kit that had a bit larger rotors but required 4.75 backspacing. Live and learn

Wait, backspacing of 4.0 or less is correct, I always get that mixed up! So the other kit required 4.25 or less backspacing and I was 4.5

Most wheels I have seen have 4 or more of backspacing. Are there many non-custom rims with less?

When I built mine it seemed like 4 - 4.5 was pretty much the standard, and I found plenty of 4.5 options. I just did some quick looking and there are tons of non-beadlock at 4.5, when I look for 4.25 and lower the options drop off very quickly but they are out there. In Beadlocks there are a fair amount of options all the way down to 3.5.

I special ordered my rims for the Samurai with a 1" back space. Just throwing the info in there. (doesn't apply to Jeeps....) 😉 It was so I could get steering clearance for the leaf springs

I have a metal cloak kit, and I run 3.5" backspacing. No rubbing here.

Unfortunately Method doesn't sell a 3.5-4" backspace in the beadgrip style, only 4.5+. There are other brands with the extra thick safety bead which act similar to the beadgrip like teraflex but I haven't shopped for that specific backspace requirement.
