Hub-centric wheels are designed for the hub center bore of the wheel to be a perfect match to the vehicle. This allows the wheel to be centered on the vehicle hub, which is the most accurate way to center the wheel. Most original equipment wheels are designed to be hub-centric because the manufacturer designs wheels specifically for each vehicle.

I presume that Cray could make hub-centric wheels for Corvettes, but that's not the way our factory wheels are done.
Here's the discussion from the C6 section, C6 wheels mount the same as C7 wheels.

Hello,
I see a lot of back and forth on this question. Just want to clear things up. They are not hub centric. The wheels are centered on the stud and are lug centric.
A hub centric wheel is centered upon installation by the machine fit over the hub, hence the term, the OEM wheels on the ‘Vette are lug-centric, meaning that they are centered by the lugs making it critical that a proper torque sequence, on jack stands, is followed. Not properly following the torque procedure will result in an off center wheel and a vibration concern. Hope this helps.

Perhaps my understnding of hub centric is off. My OEM and Cray wheels fit tight to the hub such that the lugs and threads align without any wiggle room.
I agree the strength comes from tightening the lugs to support the weight (and keep the wheels from flying off).
