Claim:
A vehicle wheel comprising: a disk and a rim having a well portion and fixed to the disk for supporting a tire for the vehicle; and an additional air chamber member secured to an outer circumferential surface of the well portion in a tire air chamber defined between the rim and the tire, the additional air chamber member comprising an additional air chamber and a communication pipe with a communication through hole therein for communication between the additional air chamber and the tire air chamber, the additional air chamber having a peak in a radial direction of the vehicle wheel and the communication pipe protruding from the peak in a direction substantially parallel to an axial direction of the vehicle wheel, wherein a radius D 2 of rotation of the vehicle wheel at the tip of the communication through hole is equal to or greater than a radius D 1 of rotation of the vehicle wheel at the peak of the additional air chamber; wherein the additional air chamber member comprises an outer plate which is curved such that there are different distances between portions of the outer plate and a rotation axis of the wheel when viewed in a cross-sectional view taken in a direction parallel to the rotation axis of the wheel, and wherein the largest distance occurs at the peak.
