To provide an automobile wheel that exerts an effect of reducing cavity resonant noise generated in a tire-internal space while an automobile travels.
The automobile wheel 1 includes: first bottom parts 13 provided inward in a radial direction of a front side bead seat 12a and a back side bead seat 12b between the front side bead seat 12a and back side bead seat 12b; and second bottom parts 31 provided inward in the radial direction of the first bottom parts 13. The first bottom parts 13 and second bottom parts 31 are alternately provided in a circumferential direction. This configuration increases difference in area between area of a cross section Sb in the radial direction of the tire-internal space P in sections where the first bottom parts 13 are provided and area of a cross section Sa in the radial direction in sections where the second bottom parts 31 are provided and thus allows improvement in the effect of reducing cavity resonant noise.
