Odd Death Wobble Issue

I have an 07 JKUR with 37" KO2's on stock JL Rubicon wheels on it...I can run 80mph down the interstate no problem. When I put on my 39" Krawlers on KMC bead lock wheels, I can't get much past 35mph and it goes bezerk.

I've been pondering something loose, caster, toe-in/out, something this, something that, etc. These wheels are new-to-me and look fantastic. They were still mounted on the Gladiator the guy I bought them off of had, and have only minor rash on the rings.

I did not balance these, I put 14oz of beads in each and assumed it would get me awful close and I'd adjust from there. Did I underthink that part of it?

I'm struggling to think it's suspension related given the ZERO issues with 37's?

Thoughts?

Are you talking Reds? Why would you ever need to go over 35mph on the street on a set of Krawlers? And why would you drive these on the street other than very short distances in the first place?
 
OK, I appreciate the advice, I will get the beads out of there and take him to a shop and we’ll see how close we can get with them. And by the way, these are blue DOT 39s.

I certainly don’t need to go 80 miles an hour in them, but it would be nice to be able to roll down the highway 55 to 65

These tires are a badass design, but I wonder if such large spaced out lugs may contribute to them being difficult to balance. I know of a guy here that runs a set of blues and they are balanced - I've driven it too fast so it can definitely be done
