The Grade 8 bolts are what Method supplies with the wheel and ring combo. I assume they have tested it and found it to be what works best. The bolts are threaded all the way to the heads, so no shoulder. I did locate bolts with a shoulder, but it seems they would be right on the edge of having...
Looks like the tire shop may have used some silicone as well.
This is the ring ...
I spoke to the local 4WD shop that helped with the suspension install. They are Jeep guys, but they know tires and beadlocks. As soon as I told him what was happening he said spacers are the answer. Ordered...
