For enhancing the visual effect of the arcuate segments being moved away from each other, edges of the arcuate segments are provided with projecting parts that are obscured when the arcuate segments are in the first position proximate each other.

Abstract: A toy wheeled vehicle such as a toy truck which is intended to be pushed along by a child includes electronic circuitry which is capable of emitting a plurality of different sounds similar to the sounds of a real truck. The actual sound of a truck's internal combustion engine is digitized and stored in a microprocessor along with other sounds such as those generated by a starter motor, horn, backup beeper and the like. In addition, the microprocessor is capable of synthesizing additional realistic vehicle sounds such as those generated by air brakes and the like. A starter switch first activates the starter motor sound and then the engine sound at idle speed. A speed sensor senses both speed and direction of travel and varies the engine sound in response to the sensed speed. The backup beeper sound is automatically generated along with the engine sound when the truck is moved in reverse. The microprocessor not only stores all of the digitized sounds but also controls all of the operations of the truck.

Abstract: A toy vehicle wheel that changes from a generally cylindrical periphery with an initial diameter and axial width to a greater diameter periphery. The wheel has a hollow shell of rubber or some other flexible material and opposed sidewalls of the wheel are moveable relative to each other to compress the axial width and increase the diameter.

Variations provide for containing the axial screw within the compressed wheel or permitting it to extend out of a sidewall. Other forms provide for movement of the sidewalls relative to each other with bayonet locking in a desired condition and for spring bias in one direction.
