The big hole in the middle of the rim is the center hub hole and it fits on the hub of the brake rotors. A Hub Centric Ring is used on a wheel where the hole is too large for a particular application. The HCR is used to make the hole smaller. All car makes have a different size brake hub so Wheel companies make one size hub hole on their wheels and use a HCR to make it fit. For example - The Wheel company makes their rims with a generic size 75mm hub hole but to fit that wheel on a car with a 65mm hub they have to install a 10mm hub centric ring, thus reducing the size of the center hub. Hope this helps.
