PROBLEM TO BE SOLVED: To provide a tire for a two-wheel barrow, in which a tread combines wet grip performance with wear resistance.SOLUTION: The tire for a two-wheel barrow is provided which comprises a pair of bead portions and a pair of sidewall portions and a tread portion continuous with both sidewall portions, and in which the tread portion is divided, in the tire width direction, into three portions by a center portion including a tire equator surface and a pair of shoulder portions including the tread ends, wherein both tread rubber of the center portion and tread rubber of the shoulder portion include a rubber component, and satisfy the following expression (1). (The peak temperature of a loss tangent tanδ of the tread rubber of the center portion)<(the peak temperature of a loss tangent tanδ of the tread rubber of the shoulder portion)...(1).SELECTED DRAWING: Figure 1
