If you've ever felt steering wheel vibrations after installing new wheels, hub centric rings might be the fix. These little plastic rings fill the gap between your car's hub (the part that sticks out) and the center bore of your wheel. This set has an outer diameter of 73.1mm (fits the wheel) and an inner diameter of 66.1mm (fits the vehicle hub). They're about 10mm thick. By ensuring a precise, snug fit, they help eliminate vibrations, improve ride smoothness, and reduce stress on lug nuts. Made from durable plastic, they're easy to install—just slide them onto the hub before mounting the wheel. They're suitable for many cars where the wheel's center hole is larger than the hub. Always check your vehicle's hub size and wheel bore before ordering. A simple, affordable upgrade for better performance and safety.
