Vehicle wheel information supply device and wheel tire abnormality indicating device

A vehicle wheel information supply device for supplying wheel information relating to a state of a wheel of a vehicle, including a wheel state detector for detecting the state of the wheel, a wheel information generator for generating the wheel information relating to the state of the wheel, on the basis of an output of said wheel state detector, a transmitter for transmitting said wheel information, and a receiver which receives said wheel information transmitted by said transmitter, said wheel state detector, said wheel information generator and said transmitter being disposed on said wheel while said receiver being disposed on a body of said vehicle, wherein an improvement comprises:

• said wheel information generator being capable of generating wheel information having respective different volumes;
• and
• said wheel information generator including a wheel information supply control device for controlling at least one of an operation of said wheel information generator and an operation of said transmitter, for thereby controlling a condition in which said wheel information is supplied, depending upon at least one parameter indicative of said state of said wheel, which at least one parameter is detected by said wheel state detector.
