I recently purchased some Method Beadlocks at a decent price. They should keep the tires from spinning on the wheel. Their are multiple wheel companies that make them like Trail Ready, Method race wheels, Walker Evens, XD Enduro, and I believe Ultra wheels just released some.
I ended up using "right stuff" on all four rear wheels and then using the tire screws up front with more "right stuff" to get them to seal up. Seems to be holding now.
