It's not so much that bead locks are illegal, it's that they are not legal.
In order to be on the road, your wheels need to have DOT approval. Since most bead locks do not have an outer bead, they just squash rubber lip between two pieces of metal, they can leak just because of the design. Thus there is not an 'error free mounting system' in place, and thus no DOT approval.
Not that you can't run them on the road. Just if you get in an accident and they claim your tires where to blame...
Never heard of anything like that here in the US. The only thing I do know is that it is illegal to run Beadlock wheels on the road in the US...and also non-DOT approved tires.
I have read several threads on the beadlock wheels and their legallity (mostly on pirate).......no one has ever came up with a source (a law) that states that they are illegal. Has a new law been passed recently that makes them illegal?
I couldn't tell you to be honest. All I know is I have NEVER seen a set of beadlocks on any vehicle driven on the road, except for an H1 style Hummer. I don't believe there is a set "law" stating Beadlocks are illegal, however, anything that is not Department Of Transperation (DOT) approved then it is not road legal...be it wheels or tires...and so far, other than the Hummer wheels, I don't believe there is a Beadlock wheel that has been DOT approved
IIRC, the so-called non-DOT approval is what they were discussing on most of the threads. The bottom line was, the wheels they make the beadlocks out of had the DOT approval stamp on them and therefore there was no issue (even though the wheels had probably been modified after the original DOT stamp was added). And no one had any proof that anyone had ever been written a ticket for beadlock wheels.
Another point that was brought up.....there are enough fake beadlock wheels out there, it would be very hard for the common officer or DOT official to determine if they are actual beadlocks or not, without close inspection.....so unless they were looking for beadlocks specifically (as if most even know what beadlocks are), then most woudn't even give them a second look.
Not looking to argue about it.....just reiterating what I have read on the beadlock discussion.
From some of the heaps of sh!t I have seen out on the road, whether or not beadlocks are DOT approved should be the least of their worries.
