So when I first bought the wheels for my car they told me that the way the hubs were the wheels would not center themselves so they had to get me "self centering lug nuts". So before I got the lug nuts I had significant vibration on the freeway. After they installed these lug nuts I still had this issue. I've now taken off and put back on every wheel numerous times. I greatly reduced the vibration but it still bugs the hell out of me! Anyone have any ideas to eliminate the vibrations?
