Hub Rings
Hub rings are also said hub centric rings, are designed to fill in the gap between the hub of the car and the center bore of the wheel. Most aftermarket wheel manufacturers design their wheels with a centerbore large enough to fit on most cars. These wheels have a larger bore diameter than the hubs of the vehicles they are made to fit onto, as a result they are not hubcentric to your vehicle which causes vibration. Made from durable heat resistant materials hub centric rings fill this gap and ensure the Wheel is installed perfectly centered on the vehicles hub which helps to eliminate the vibration.
