I had the tires mounted on a new set of eurotek 19' wheels and when the shop went to put them on there were fitment issues with the hubcentric rings as they were too tight and deforming and couldn't get the wheels to sit flat against the hub of the car. Now when I drive on the highway I get a nasty vibration and wobble. The wheels were properly balanced so it's definitely the cause of the plastic rings not fitting properly causing the wheel not to sit flush. Any help on what you owners did to remedy this issue?
