^^I'm not taking ity personally.... Thing is, there are 2 schools of thought. One, where the lugs do the job and all should be good. I agree, it should work that way.
Two, the lugs don't "totally" do the trick and wheel's up/down vibration hoses up the nuts/studs/balancing, etc.
I've done the homework, somewhat debated with the 2 schools of people, etc... Bottom line is that once the rings were back on, we have not even had a lug nut come loose.
For $10, just do it. Measure the difference between the hub and the wheel and just adequately fill the space. The wheel was made for a 73mm hub. It was about 10mm of space that the lug nuts were supposed to equally space. I don't think the lug nuts totatally did the job.
Now that the space is filled with a ring (metal one that the tire place provided), none of the symptoms are there anymore. Same type of lug nuts.
Maybe it's the lug nuts used, maybe it's coincidence... It does not matter. I am not worried about it anymore and can now focus on fxing the damaged fender/wheelwell on the wife's 94. Had they not provided the rings, I would've ordered more... even if it was just for my peace of mind.
FYI, we've had aftermarket wheels on most of our cars and I always make sure that the proper torque is used. No wheels have flown off of any of our other cars, or mysterious loose lug nuts, or broken studs.
