A non-pneumatic tire for a wheeled tower of an in-field irrigation system has a circular array of hollow cavities within the tire body. In cross-sectional planes lying normally of the rotational axis, each cavity has a circumferentially elongated cross-section of greater circumferential length than radial width. Bulbous and concavely rounded terminuses of each cavity impart a dumbbell shaped cavity profile that omits stress failure points. The cavity width tapers in an axially inward direction toward a midplane of the tire, where the cavity width is narrowest.
