One thing I noticed with my Konigs and my hubcentric rings,
63.5mm is what I got but they were loose in the front.. I had been torquing down to 94ft/lbs, but I had a vibration that was coming and
going.. the wheel was shifting a little bit(my assumption at least)
I just recently torqued to 100ft/lbs and now its smooth as can be.
I think that little extra bit was enough to pull the wheels center.
