Abstract
A wheel for a vehicle includes a plurality of Helmholtz resonators each including an auxiliary air chamber communicating with a tire air chamber through a communication hole. The Helmholtz resonators include one or more first Helmholtz resonators set to have a silencing characteristic for a first-order resonance frequency of air column resonance noise in the tire air chamber, and one or more second Helmholtz resonators set to have a silencing characteristic for a second-order or higher-order resonance frequency of the air column resonance noise.
