Just out of curiosity, I used ours (for our band trailer) on the smart wheels, and it worked just fine. While made for the slotted wheels on our trailer, it fit in the nine spoke wheel just as well.
However, the class way to steal a booted/clamped trailer with a hitch ball lock is to winch it up on a flatbed. The smart would probably be amiable to the same approach, if anyone tried to lift one.
