All modern cars use hubcentric wheels. It's a far more accurate way to
locate the wheel on the hub, which reduces vibration. The load is also
distributed over a greater area for increased strength.
Most high quality aftermarket wheels use metal rings, not plastic. The
plastic ones I've seen aren't made with a high enough degree of accuracy to
really do much to eliminate vibrations on some cars.
