Method Wheels hubcentric ring that reduces a 121.1mm hub bore to 116.7mm is a precision-fit adapter for centering wheels on a marginally smaller hub opening. This ring brings the wheel center bore from 121.1mm down to 116.7mm to improve concentricity and reduce vibration, providing a snug hub-centric fit where a small diameter adjustment is required.
