ABSTRACT:
The present invention provides a toy car wheel with an adjustable center of gravity. The middle of the toy car wheel defines a through hole. At least one spoke is distributed between the rim of the toy car wheel and the through hole. At least one channel is defined in each spoke. At least one spherical body is disposed in each channel. When a toy car decelerates, a momentum of the toy car decreases, the at least one spherical body descends in a corresponding channel, and the center of gravity of the toy car wheel descends.
