No. You're thinking hubcentric spacers. Rings simply adapt the bore of the wheel hub to the hub on the car. The don't move the wheel away from the hub at all.

Appreciate the useful info posted, I bought a '94 540i three weeks ago, and during test drive, no shakes. Next morning, the car shakes and vibrates badly at exactly 40mph. Got wheels balanced, seemed to fix. But next day,
shakes came back. Then I noticed that after driving for a while, the shakes diminish and almost disappeared. For the last weeks, it seems that the tires are "out of round" in the morning, and after tires warm up, there's no shakes. Just a theory. Might test it out one weekend by putting car on jackstands overnight. The BMW chassis is good and stiff, and it's probably sensitive to particular harmonic frequencies, like at 40mph.

Rayp, the tires are flat spotting which is common with a lot of tires. have to ignore it, as they get a little older/harder they wont do it as much.
