There you go, Fastman I agree with you 100%.
The rule probably came about when someone had a 10 gauge aluminuim wheel which they left on the car over a year or maybe two, and the combination of the disimiler metals along with the salt made for a bad electolisis problem and the wheel failed at speed. So the rule was written to combat that issue. The mag type 3/4" thick aluminum wheels were not intended to fall under this, mounting them any other way than the manufacturers intent is not good.
Jimmy's fix would get you past the inspector with no common sense, but that is about all it is doing, maybe giving you a lower center of gravity, with the extra wieght.
I found the correctly tapered 1" lug nuts, for mine but the tapered hole is recessed about an 1/8' inch and it eats up two much of the lugnut lands to properly torque with the bigger socket.
