i've seen people post wheels on ebay and stuff and they always go the are BMW hub-centric..........what exactly does hub centric mean?........what happens if the wheels aren't hub-centric?

maybe they are talking about that they are designed just for the bmw lug pattern, but not postive....

I believe that "hub centric" refers to the design of the wheel hub which if you take a look at it, has a ring of metal protruding out just inside of the bolt holes which fits inside a similar sized hole in the center of the wheel. I believe this "hub ring" carries the majority of the weight and stress of the wheel connection to the hub and helps with centering. Perhaps some one can provide a more elegant or correct explaination.

In the meantime...hope that helps!
