Repeat-Repeat-Repeat - Say it Enough Times Maybe Someone Will Believe It
This so-called "problem" has been discussed in at least three hijacked threads and valid answers and corrective action has been obtained from PT, the chasis and wheel manufacturer.
If it bothers you so much, correct it yourself. You yourself stated that you can get a set of lug-nuts for $24 - compared to the cost of most repaits on a TT, that's cheap.
Moderator - Lets lay all this to rest and close the threads where it is being discussed - particularly the threads that were hijacked from people wanting and needing real help.
