To provide a wheel having a reduced weight while maintaining quietness during the load rolling of a tire by more adequately shaping air chambers.
The wheel 1 includes an annular space 5 formed radially inside of a bead seat 4a of a rim 3 while extending along the bead seat 4a, and partitioned into the plurality of air chambers 7 via a plurality of partition walls 6, and communication parts 8 formed in the air chambers 7 between the air chamber 7 and a space 10 radially outside of the rim 3, the air chambers 7 and the communication parts 8 constituting a Helmholtz resonator. The annular space 5 consists of an area 11 having a large cross section and an area 12 having a small cross section. The partition walls 6 are arranged in the area 12 having the small cross section.
