double bead locks don't burp air or suck in dirt and mud. You can also drive on a flat to get off the trail with no worry about the tire falling off the rim. The military only uses double bead locks (some with run flat inserts) for a reason. When the 'ish hits the fan, you gotta be able to get out of there. I got double bead locks for those reasons, and I liked the style of the wheels better than other single bead lock wheels. Sure it's overkill, but overkill is good when it comes to getting off the trail and not having to ever mess with a bead on the trail.
