What does the term "hub centric" mean? |

It means that the hole in the center of the wheel fits precisely over the hub of the drum, rotor or axle. The hub is more concentric than the studs so the wheel is therefore more concentric to the center of rotation. Also, wheel studs are really only supposed to be loaded in tension, not in shear. Having the wheel fit the hub precisely keeps the studs from being loaded in shear as the hub to wheel fit can support the weight of the car even with very little clamping load from the wheel studs. |

So it would make sense that the best way to go would be to find a set of wheels that ARE hub centric then, huh? |

Most aftermarket wheels will not be hub-centric, but more and more I've been seeing hub centric rings that fit between the hub and the wheel's center bore. I have rings for my RX-7's 17" wheels. My Mustang Mach I wheels were machined from the slightly small Ford center hole to fit my Dart which also happens to work for my Dakota. All the 15x7" wheels I used on my '66 Dart road racer were OE Chrysler so they were all hub-centric.
