just as an asside, with the exception of a very few specials such as slot mags, all lugnuts regardless of type should only contact the wheel on the taper. The taper ensures that the wheel is aligned properly, and doesn't sit on the stud at all, it also prevents the nut from coming loose..
these are for slot mags only - note there is no taper at all..
FWIW, slot mags are beeeeyatches for wobbling, and running out of true.
