I suspect there are enthusiastic users of security nuts here - maybe they just don't have much to add. For different situations from mine, I'm sure they make perfect sense.
Even if no one is currently using them, owners with alloys can still answer the question about which nuts fit, since security and normal nuts fit the same way.

I get the logic, but I don't see these wheels being sold for use on a car or truck. The 5-on-4.5" bolt pattern is quite common, but non-hubcentric wheels and wheels with zero offset don't fit any car built in a long time, and 15" wheels are now of little interest for trucks (especially in a narrow width with zero offset).
Of course, my reasoning assumes a thief bright enough to research which vehicles the wheels would fit, and neither intelligence nor reason are particularly characteristic of petty criminals.
