I have not heard that, but I can say that the shop that sold me the wheels did put a good amount of balancing weights on it. Perhaps for good reason, as I cannot complain about my ride quaility. I live in an area with really rough roads and the wheels are not loud and rough as compared to some other cars I've riden in. They take bumps fine, and I was always careful to avoid potholes and take big humps carefully. Either way, several different shops have different techniques to balancing and if you are not satisfied, complain and have them gurantee their warranty of service.
