Vehicle tire-wheel assembly

A vehicle tire-wheel assembly comprising:

• a wheel main body;
• a Helmholtz resonator provided on an outer peripheral surface of a well portion of the wheel main body;
• a tire attached to an outer peripheral surface of the wheel main body so that the tire covers the Helmholtz resonator;
• and
• a separation restraining part which, in cooperation with the tire, restrains the Helmholtz resonator from separating from the outer peripheral surface of the well portion,
• wherein the wheel main body includes a first vertical wall and a second vertical wall located spaced apart from the first vertical wall in a wheel width direction with a predetermined interval therebetween, the first and second vertical walls standing from the outer peripheral surface of the well portion outwardly in a wheel radial direction and extending in a circumferential direction of the well portion, the first vertical wall having a side surface inclined toward the Helmholtz resonator,
• wherein the Helmholtz resonator includes a main body portion disposed between the first and second vertical walls of the wheel main body,
• wherein the main body portion includes a bottom portion disposed along the outer peripheral surface of the well portion, a first side portion located in one wheel width direction end portion of the main body portion and disposed along and in contact with the side surface of the first vertical wall, a second side portion located in the other wheel width direction end portion of the main body portion and disposed along and in contact with a side surface of the second vertical wall, a top portion located opposite to the bottom portion, the bottom portion, the first side portion, the second side portion, and the top portion together defining a substantially rectangular shape in a cross-sectional view orthogonal to a longitudinal direction of the main body portion, and
• wherein a radial direction outer side of the other wheel width direction end portion of the main body portion of the Helmholtz resonator is held down in a radially inward direction by the separation restraining part in cooperation with the tire.
