To ensure optimal performance and safety, start by carefully aligning the hub centric alignment rings with the hub. These rings are designed to fill the gap between the wheel's center bore and the vehicle's hub, ensuring a snug fit. Once the rings are properly aligned, proceed to mount the wheel onto the hub. This process helps to eliminate any vibrations that may occur due to an imperfect fit, providing a smoother and more stable driving experience. By following these steps, you can enhance the overall performance and safety of your vehicle, especially when navigating challenging terrains. This set includes several rings, each designed to fit specific dimensions (56.1-54.1).
