Intermittent vibration at highway speeds. Brought to the BMW dealership and they stated the right front wheel was out of round. I never hit a pothole or anything that would cause damage. The dealer "repaired" the wheel, but the problem still exists. Brought the vehicle back and am now told that BMW has started offering non-run flat tires on new cars. I feel that the run flat tires coupled with the low-profile wheels could be the issue. Also, feel that the wheels are poorly made and are prone to being warped.
