The spoke structure has a tread-side annular component, a hub-side annular component, and spoke plates radially extending from the hub-side to tread-side components, each spoke plate has thickness having first tapered-thickness region, second tapered-thickness region and minimum-thickness region such that the first region radially extending outward has the thickness gradually reducing from first position at which the hub-side component is bonded, the second region radially extending inward has the thickness gradually reducing from second position at which the tread-side component is bonded, and the minimum-thickness region has the minimum thickness between the first and second regions, and the first and second regions are formed such that each of tire radial lengths of the first and second regions is at least 0.05 times a tire radial length of a spoke plate.
