The Hub Centric Ring is a ring made of plastic or aluminum to fill the gap between car hub and wheel center bore. if your car is with OEM wheel from the car manufacturer, you don’t need this. But if you are trying to install a set of nice aftermarket rims onto your car or replace a set of wheels which was made for other brand car, most likely the center bore parameter will not fully matched with each other. The car will have vibration issue when the speed is over 40-60mph no matter how you tight up the lug nuts. The Hub Centric Rings will Fix this vibration.

Different car come with different Hub Diameter. From 54.1 to 72.6 for most of cars, Light trucks are bigger. Even different model or year made of the car under same brand may have different Hub size. if you have no idea of your car parameter. Provide your car model and year made. We will check that for you.

Most of the aftermarket wheel come with bigger Center Bore. The manufacturers want to fit their wheels with many cars. The CB data can be found from Wheel brand website or from the carton label of the wheels. if can’t find the data, try to measure the Diameter using a Caliper.

The Outer Diameter (O.D) of the hub centric ring must match with Wheel Center bore. and the Inner Diameter (I.D) must match car hub diameter. the tolerance can only within +-0.2mm.

Both plastic and Alloy Rings work perfectly if you choose the right size. Alloy one is nicer for the appearance. And it is made by CNC machine, tolerance can be controlled within +-0.1mm. The plastic one is made from Injection molding. The tolerance is within +-0.2mm. But it is cheaper than Alloy one.
