2 layers of duct tape and bead sealer. I run 6 psi on spyder lock wheels with no inner bead issues. Even after cutting a side wall and driving about a half of a mile back to the truck. The inner bead was still on. Dismounting is a real pain.
Flange bolts and nordlocks. shoulder of the bolt needs to fit snug in the axle flange, or the axle will work back and forth causing the bolt to loosen.
