Alright, since I could not figure out what was causing my slight vibration and weird "whurring" noise coming from my new rims, I decided to buy new rear tires to hopefully fix the problems. I have a question. Are these the correct rings you are supposed to use with e39 rims?? http://cgi.ebay.com/ebaymotors/BMW-H...spagenameZWDVW (These are the rings that are currently installed with my rims). Is the ring supposed to cover the entire hub, or just the extra 2 mm or so?? My rings do not cover the entire hub. Once again, is there any possibiblty that I'm rubbing against the control arm?? There is only about 1 finger width of space between the tire and control arm (I think that's what it is). Thanks for your time guys.
