<P>PROBLEM TO BE SOLVED: To provide a maintenance-free vehicle wheel capable of keeping reduction effect on noise sound generation for a long time period. Ž<P>SOLUTION: In the vehicle wheel, a sub-air chamber member (13) for forming a sub-air chamber (SC) in a tire air chamber (MC) is fixed on an outer peripheral surface of a well portion (11c). In a cross-sectional view along a wheel radial direction, a radius D2 of rotation at the tip portion of a communication hole (13b) provided in the sub-air chamber member (13) for communication between the sub-air chamber (SC) and the tire air chamber (MC) is equal to or larger than a radius D1 of rotation of the vehicle at the peak portion of the sub-air chamber (SC): (D1≤D2).
