Sorry...it means that the center of the wheel indexes perfectly on the 
protrusion on the hub.   You could remove all the studs, lay the wheel in place 
and spin it and it would stay perfectly centered.

Lug-centric wheels rely on the conical face of the lug nuts (or lug bolts 
on German cars) to center the wheel, and the center of the wheel doesn't 
touch the protrusion on the hub.

Adapters are available to allow a lug-centric wheel to index properly on 
this protrusion.   Here's a nice example:

These rings are widely available from any good tire store, Tire Rack, 
Amazon etc.   All you need to know is the outside diameter of your hub, and the 
inside diameter of your wheel center.   

Tire Rack says this on the subject:

Make certain that the wheel's installation hardware is correct for the 
vehicle and in good condition. Since almost all of today's cars are designed 
with hub centric wheels which transfer the vehicle's load from the center of 
the wheel to the car's hub (and allow the lug nuts/bolts to just hold the 
wheel against the hub), it is important that track wheels continue to be hub 
centric to help distribute the forces encountered on the track. If an 
aftermarket wheel requires special centering rings to properly fit it to the hub, be 
sure they are installed and installed correctly.
