No problems here. When I had them put on a few years ago, they were legal in CO at the time. They are however illegal in Utah. They don't care in Moab, but I've heard reports (of questionable reliability) that the State patrol lookes for them on I-70 around Easter. I talked with the guy that did mine, he said (and I agree) that it's not the greatest idea for a daily driver, but occasional use shouldn't be a problem. I have the old (circle track) style MRT bead locks. Before I got the trailer, I used to drive it ot Moab on the old 35s, then switch them when I got there.
