A wheel system for a vehicle body includes a control device and a wheel assembly. The control device stores multiple warning conditions, and multiple warning parameters corresponding respectively to the warning conditions, and is configured to detect a target object in the vehicle body so as to generate sensing data. The control device is further configured to, when one of the warning conditions is met based on the sensing data, obtain a corresponding one of the warning parameters that corresponds to the one of the warning conditions, and output a control signal that includes the corresponding one of the warning parameters. The wheel assembly is configured to receive the control signal from the control device, to emit light with one of multiple color patterns which corresponds to the corresponding one of the warning parameters included in the control signal, and to generate electric power.

A wheel assembly that provides a simulated center lock wheel look that also enables exchanging of ornamental face plates with a center hub attachment device that will allow car enthusiasts to easily change the look of their automotive wheels while maintaining a center lock wheel appearance. The assembly includes three components: a base wheel, a plurality of ornamental face plates, and a center hub attachment extending from one of either the hub or the ornamental face plate.
