TIRE

A tire includes a tread portion provided with a block . A block corner portion of the block has a stepped chamfered portion formed therein in which a block height decreases stepwise from a tread surface toward a top portion . The stepped chamfered portion includes upper surfaces parallel to the tread surface , and step corner portions each formed so as to protrude toward a block outer side as a result of the upper surface and a vertical surface or the vertical surface and the tread surface intersecting each other. An angle θ between the tread surface and a virtual straight line n connecting the step corner portions in a vertical cross-sectional view, of the block corner portion , passing through the top portion is 10 to 40 degrees.
