To provide a method of manufacturing a wheel having highly airtight air chambers radially inside of the bead seat of a rim, in a reliable and highly productive manner.
The wheel includes an annular space formed radially inside of the bead seat of the rim while extending along the bead seat, and partitioned into the plurality of air chambers via a plurality of partition walls, and communication parts formed in the air chambers between the air chamber and a large space radially outside of the rim, the air chambers and the communication parts constituting a Helmholtz resonator. In manufacturing the same, a tube is inserted through the communication part into the space, and a sealing material is supplied via the tube to form the plurality of partition walls.
