Balancers do not center…adapters do. Without the right adapters, used in the right way, wheels are not centered meaning a zero on the balancer doesn’t necessarily mean the wheel is balanced. Weight can be added and removed and added again until you get zeroes but then what about repeat-ability? And why are there more and more wheels that balancers just can’t balance? For balancers to do what they are intended to do, wheels must be centered and mounted on the balancer exactly as they are on the vehicle. In today’s marketplace, it is important to consider both hub centering and lug centering on every wheel so that wheels are always mounted correctly on the balancer. Not only will this optimize the balancers ability to balance but also allows shops to provide truly balanced wheels to their customers. Mount wheels properly, and vibrations, chasing weights, false zeroes and comebacks become a thing of the past.
