Abstract
A work machine tire includes an annular body of elastomeric material that includes a middle radial region. A plurality of unpressurized cavities are defined by the middle radial region and are distributed in a pattern that includes a first radial band of cavities and a second radial band of cavities. Each cavity of the first radial band of cavities is oriented at a positive angle with respect to a radius therethrough, and each cavity of the second radial band of cavities is oriented at a negative angle with respect to a radius therethrough. A material volume of the middle radial region is more than one and a half times greater than the combined void volume of the plurality of cavities.
