So let me get the straight, Stazi. What you are saying is that the friction from the hub/wheel interface (that he just proved to be so strong) will overwhelm the centering force that the tapered lug nuts have, and leave the wheel off-center, just a little bit? That without a hub-centric ring to get that position right before the nuts are tightened, the tapered nuts get it close, but not close enough, since they lack the leverage to center the wheel that last little bit once they start squeezing the wheel on the hub? Makes sense to me. As a matter of fact, I could prove that this happens, using the equations he gave, if he feels you have too little experience with wheels to know what you are talking about.
