The term "HUBCENTRIC" is a phrase based on the European "24 hour Le Mans" races from over 50 years ago-
In the old races they used "HUBS" with a ctr shaft and no lug studs-hence "HUBCENTRIC"

THe lower photo shows conical wheel studs which can keep the wheels centered on the hub without the having a hub centered wheel. With a hubcentric wheel the load is carried primarily by the hub and the lugs basicly hold the wheel on. With a conical lug and hub centric wheel the load is still primarily carried by the hub. With a conical seated wheel that is not hub centric the lugs, via the conical seat, center the wheel on the hub, and the weight is carried by the lug bolts; this is ok as it has been done for years with aftermarket wheels.
This is a true hub centric set up.
These are conical lugs that are OEM.
Absolutely "RIGHT", but no US auto wheels are sold that way nowadays
The only reason you SHOULD care about the "Hubcentric" wheels nowadays, is to make sure they will actually fit over the hubs on your jeep/car/vehicle-
A lotta guys willo get a deal on used wheels and they won't fit over the "HUBS"
The 4/5/6/8 studs, are what actually centers and secures the wheels --
