An off-road motorcycle-tire (2) includes a tread (4) having shoulder blocks (18c), and sidewalls (6). Each shoulder block (18c) includes a main portion (20) and an end portion (22). The main portion (20) is formed by a first crosslinked rubber composition. The end portion (22) and the sidewalls (6) are formed by a second crosslinked rubber composition. The JIS-A hardness Ha of the main portion (20) is greater than JIS-A hardness Hb of the end portion (22) and the sidewalls (6). Difference (Ha-Hb) is greater than or equal to 5, and is not greater than 12. A ratio (H2/H1) of a height H2 from a boundary point Pb between the tread (4) and each sidewall (6) to a boundary point P2 between the main portion (20) and the end portion (22), relative to a height H1 from the boundary point Pb to an outermost end P1 of a corresponding one of the shoulder blocks (18c) in the axial direction, is greater than or equal to 1/3.
