vibration coasting down hill
I have a 2011 X3 I just put a set of winter wheels and tires. I took a bit but finally got them balanced perfectly smooth as can be right up to 80 MPH, except going down hill. When I back off the throttle at highway speed coasting down hill I still have a strange vibration. I is not horrible but noticeable. I did not notice the vibration with the stock wheels and tires.
Has any one else experienced this issue. Any suggestions?
