I have a set of Raceline Monster Beadlocks and some Falken Rocky Mountain ATS tires in the 35x12.50x15 flavor. These tires and wheels do not work together! Ever since I bought the tires we have not been able to balance them, one of the tires wanted a pound of weight! What I have discovered is that the diameter of the tire bead is too large and will not center the tire on the wheel. I called Raceline and they basically told me to pound sand and that it was the tire, they were actually quite rude to me. I have tried to call Falken but no one has ever answered the phone. I know a lot of you guys run Falkens and Raceline wheels and if anyone else has had these issues and what you did to fix it? The lip that the bead should fit tightly over has a gap of about 1/8". I really hate to buy new tires or wheels...
So, with the lock ring installed, is there an issue keeping the tire on the rim ?
No, the issue is the tire will not center on the wheel and therefore you cannot balance them. If you look at the picture you can see the gap between the bead and the lip on the wheel. Every other bead lock I have ever mounted you have to pry the last few inches of the bead over the lip and that is what centers the tire to the wheel.
With the tire rim combo on the balance machine, is there visible or measureable runout of the tire ?
Visibly you can see the tire is not "round" with the wheel, that is on the balance machine you can watch the bead lock ring go around with little to no run out and you can see the lines on the tire have at least 1/8" difference in them.
I suggest you take them to an independent tire shop and get the answers you seek. Retail tires stores with advertised brand names are helpless and clueless when faced with anything that isn't 100% stock. My tire shop works ATV and trailer tires, farm tractors, bucket loaders, skid loaders, and any on-road vehicle with tires, including 18 wheelers.

CJ7-Tim, maybe you are not understanding what I read!!! Krazytoy is saying that the inside bead diameter of the Falken is a 1/4" smaller than the diameter of the lip on the beadlock wheel therefore having a 1/8 gap between the tire bead and mounting lip of the Raceline wheel!!! as seen in pics. I understand where Krazytoy is coming from as there is nothing that will center the tire on the wheel creating a major balance issue since the tire bead has a 1/8" gap from making contact with the wheel lip!!!
Falken tires are a PITA to begin with. Took multiple technicians an hour just to mount one of my 285/75-16s onto a standard 8.5" rim. Then just recently I was at a Discount Tire store and saw the techs mounting some to a guy's TJ on stock wheels and they were using some kind of huge torch/blow gun thing to get them to take a seat on the bead and hold air. I can imagine that on fancy rims like you've got they'd be a nightmare.
Yet another reason I'll never buy Falkens again.

That's odd, I mounted my 285/70/17s on JK Moabs in my garage with two motorcycle tire levers and a pitiful homeowner-style compressor with the CFM output of an asthmatic nonagenarian wheezing into a McDonald's straw. Bead seating was a little tricky but I made it through.
OP, I'd try a local 4x4 shop that's better with beadlocks. It might take some trial and error, but I don't see how you couldn't get the tire to seat straight.
Plan B is to see if you can get a different ring with a lip that could centre the tire better?
Here is the issue I am trying to point out. I really have no complaints about the tires themselves it is just that they don't seem to fit the wheel or the wheel doesn't fit the tire. It is not a question of whether or not the tire shop can mount them correctly either, it is a size issue.
What if you mounted them (to seat the inside bead), pulled the cores, loosened the bolts on the beadlock ring, then re-tightened with the hopes that the one centered bead would "pull" the tire straight under the lock ring?
