Abstract: A device installable on all sizes of vehicle wheels, such as automotive and aircraft, to automatically and substantially permanently compensate for wheel imbalance due to uneven tire wear, unbalanced tire construction, and other known factors which effect wheel balance. Centrifugal force activated, freely circulating weight components within the annular tube body of the device tend to remain at the balanced wheel positions when the wheel is at rest. The device is applicable to single or dual wheels and other rotating bodies subject to dynamic imbalance.
