TIRE

A tire (1) includes a tread portion (2) provided with a block (3); a block corner portion (5) of the block (3) has a stepped chamfered portion (7) formed therein in which a block height decreases stepwise from a tread surface (3a) toward a top portion (3b); the stepped chamfered portion (7) includes upper surfaces (10) parallel to the tread surface (3a), and step corner portions (12) each formed so as to protrude toward a block outer side as a result of the upper surface (10) and a vertical surface (11) or the vertical surface (11) and the tread surface (3a) intersecting each other; an angle (θ1) between the tread surface (3a) and a virtual straight line (n3) connecting the step corner portions (12) in a vertical cross-sectional view, of the block corner portion (5), passing through the top portion (3b) is 10 to 40 degrees.
