Hub centric

I just went through this exact situation, I bought used aftermarket wheels that were used on 5/8 studs, to use on my 1/2 studs. To do this I ordered shanked open end lug nuts, shank diameter of .687. The problem is the shanks had a bit of play within the hole, I did not feel comfortable with the fit. My axle registers are 2.3", and the new wheels have an opening of 3.25". I had my local machine shop make me some custom rings to properly center the wheel, the fitment is excellent. Now the lug nuts only purpose is clamping. I will post pics after work.
