I've looked around on the forums a bit to see what others' experiences have been with using differently sized center bore wheels, however I'm not having much luck answering my question. Last winter, I ran on 72mm steel wheels with no hub centric rings (it's impossible to find 72mm OD x 70.3mm ID). I didn't have any vibration problems, however I'm worried about the stresses applied to the lugs.
Given that the steel wheels are not hub centric, I'm worried about another season of shear stresses on the lug nuts. I have some hub centric rings that are 72.6mm OD x 70.3mm ID that I've tried sanding down, but the tolerances are so poor that it looks like it's a futile effort. Besides, how can a plastic ring be load bearing???
Edit: From what I've read, and what seems appropriately logical to me, is that it's the normal force created by the lug nuts tightening the wheel against the hub that provides enough static friction to handle the shear loads. Any mechanical engineers or mechanics out there who know the right answer?
Thanks for your advice.
