I found someone on pirate that had problems with these and returned them. I messaged the seller and this is what I got. Sound like bs? Should I not take a chance and return them? I have Iroks.
No. They will not work with BFG red labels. When the rig is bolted to the rim it has .600 clearance. DOT says the bead must be .750 thick. Red labels have a .625 thick bead, so that means it only clamps by .025. I measured 35' AT's at .765, 37" Lakesea tires at .800, 42 Pitbulls at .850, and 37 Goodyears at .925. We ran for 4 miles in a race with a flat and did not loose a tire. As long as you have anything besides a red label you should be good.
I also had a customer who took the rims with my tires to a Mexican tire shop to have them balanced. They did not understand the beadlock wheel and ended up cutting the sidewall of the tire before they could get the bead to break. I repeat, as long as your tire has at least a .750 thick bead there should be no problem. Most offroad tires have a thicker bead than DOT requires, but since the red label tires are not DOT, they can build them how they want.
