Hub Centric Rings



Why Do I need Hub Centric Rings?

Hub centric rings are rings that cover the spacing between the center bore of an aftermarket wheel to the hub of the vehicle. In certain cases, aftermarket wheels usually have a standard center bore size to accommodate a wide variety of vehicles. 

There are different sizes of hub centering rings and they are measured in millimeters that are available through the dealer who sold the wheels. Hub centric rings are important because they secure the wheel in place, and they ensure that the wheels are perfectly centered on the vehicle’s hub. This helps to prevent any type of vibration issue.

If your wheel center bore is a larger diameter than your hub bore, you need hub centric rings. This is because aftermarket wheels are typically designed to fit as many cars as possible unless they are custom-made for your specific application. For cost-saving reasons, mass-produced wheels will have a center bore large enough to fit the biggest hub bore that wheel was designed to fit. More often than not, when you buy a set of aftermarket alloy wheels, your wheel center bore will be much larger than the bore on your hub. While this doesn’t prevent you from mounting the wheel on your car, it is less than ideal.

What if I forego the use of hub centric rings?

Depending on the application, get ready for a bit of a harsh ride. Some cars are totally fine without hub centric rings and some respond very poorly. If you experience vibration after installing new wheels, you may need hub centric rings!

When the hub is smaller than the center bore on the wheel, the wheel will not be technically centered. This causes vibration in many cases, especially around 50-60mph, that feels like a wheel imbalance.

This is because the wheel is slightly off-center and not making a smooth rotation. With hub centric rings, you fill that void and adapt the center bore of the wheel to the hub bore of the car.

The purpose of the centric ring is to perfectly center the alloy wheel to the wheel hub and hence prevent vibration to the steering wheel during driving and the shaking which typically appears around speeds of 40-60 mph.

Wheel spacers effectively change the offset of your wheels without making you buy new wheels. They space the mounting surface away from the hub so your wheels poke out for a more aggressive fitment. Many spacers are designed with both the PCD, or bolt pattern, and center bore to be exact.
