^ That is odd. ^
Is there some safety reason why you shouldn't run them on the street? It's something I am planning for and don't like the price of the Staun internals.
It's not unheard of to shear the heads off a ring bolt. Once one goes, the rest seem to go like popcorn. The ring is the only thing holding the outer bead to the wheel. Once that goes, the tire comes off the wheel. On a trail, it's not too big of a deal but if you're running at higher speeds, it could be catastrophic. Checking the bolts periodically, would be a good idea on a daily driver. More maintenance then standard wheels or three piece wheels like the Hutchinson.
Oh another reason why most beadlocks aren't DOT approved is for liability. Kinda like how bumper companies say they're for 'looks only', they're protecting themselves.
