Abstract
A wheel for a toy vehicle includes a rim, a tire, and a ballast. The rim includes an outer circumferential surface. The tire is attached to the outer circumferential surface of the rim. The tire and the rim cooperatively define a ring-shaped receiving channel therebetween. The ballast is received in the ring-shaped receiving channel, and slidably connected to the outer circumferential surface of the rim. The weight of the ballast is greater than the frictional force between the ballast and the rim.
