Hub rings for wheels

What Are Hub-Centric Rings?

Hub-centric rings, or hub rings, are typically made of plastic or metal and help ensure that your aftermarket wheels fit your vehicle and provide the smoothest ride possible. But, do you need hub-centric rings on your wheels?

Here are some common terms used with hub-centric rings that may help explain what they do:

Vehicle Hub: Sometime called hub pilot, refers to the center of your vehicle axle on which the wheel rotates.

Center Bore: The hole in the center of the wheel that attaches directly to the hub of the vehicle.

Hub-Centric Wheels: Wheels that have a center bore that matches the size of the vehicle’s hub.

Lug-Centric Wheels: Wheels that have a larger center bore than the vehicle’s hub.

What do Hub-Centric Rings do?

Most aftermarket wheels are lug-centric, which means the center bore of the wheel is larger than the hub pilot of the vehicle. Hub-centric rings fill the gap between the wheel’s center bore and the vehicle hub. This aligns and centers the tire and wheel assembly on the vehicle. Although hub-centric rings are not required, they can play a role in minimizing vibration. Note: Hub-centric rings don’t carry any load.

While most aftermarket wheels are lug-centric, an original equipment (OE) wheel is hub-centric and doesn’t require a hub-centric ring.

Do I Need Hub-Centric Rings?

If you have OE wheels, you don’t need hub-centric rings. OE wheels are designed to fit your vehicle just right, so the hub rings are unnecessary. On the other hand, if you’re installing aftermarket wheels, (although they are not required) you can use hub-centric rings to ensure a perfect bond and minimize the chance of higher speed vibrations. If you’re unsure whether or not you need hub rings, feel free to give us a call and we can help determine if the wheels being used will accept a hub-centric ring on your vehicle.

What Size Hub-Centric Rings Do I Need?

Hub-centric rings are made in a wide variety of sizes to accomodate various wheels and vehicles. If you decide to use hub-centric rings, you’ll need to make sure they’re the right size for your wheel and your vehicle. Hub-centric rings are sized from the outer diameter to the inner diameter (measured in millimeters). The outer diameter is the hub bore of the wheel and the inner diameter is the diameter of the vehicle hub.

For example, a hub-centric ring size of 73-67.1 would mean that the wheel center bore is 73 mm wide and the vehicle hub is 67.1 mm wide.
