Is Hubcentric Rings Nec.?

[gregy]

I have E70 wheels on my E53, Ive tried two different types of hub centric rings (plastic and aluminum). While it is night and day with and without I still have a vibration right at 60MPH.

Prior to getting the rings I thought it was a balance issue. I had all 4 wheels road force balanced and the vibration was a little less. The mechanic mentioned that the rings were necessary. I got tried both types of rings and while it is pretty much the same.

I just got back from having just the fronts road forced balanced again. It is slightly better but it still shakes at 60. I am ready to put my E53 wheels back on.

Any ideas? My 19" E53 sport wheels were vibration free, new wheels are E70 wheels with latitudes run flats.
