A common thread on Pirate... Everyone likes to claim beadlocks aren't legal, but most codes don't specifically state it! Now, majority of companies simply don't go through the DOT process, which then would make them illegal. There are companies out there that DO sell DOT beadlocks.
Another positive for running beadlocks: its practical to change tires in your garage without having to have to run to a tire shop. The internal beadlocks while nice are kinda a PITA to do tire changes with (probably a little overkill for what folks around here would need, tho).
I'm looking forward to some single beadlock wheels. I recently tried out some 15's (they look killer, too), but the backspacing just kills the deal for me. Maybe some 17's down the road
