The AEV wheels are cast with the beadlock mounting ring already in the wheel. There is no welding on these wheels; it's a solid one-piece deal. The beadlock rings are knurled to keep the tires from spinning on the wheels in high-traction situations. We wish the beadlock mounting holes had steel inserts, but we can always add them if the tapped holes become a problem. Regardless, it's hard to beat the price and quality of these aluminum beadlocks.
