A block in which at least two edges are formed, namely a first edge serving as a trailing edge when traveling in a first direction DR1, and a second edge serving as the trailing edge when traveling in a second direction DR2 opposite to the first direction DR1, is composed of at least two rubber layers that overlap in the circumferential direction of a tire, wherein: the at least two rubber layers comprise a first rubber layer which includes part of the first edge and is composed of a first rubber composition, and a second rubber layer which includes part of the second edge and is composed of a second rubber composition different from the first rubber composition; the first rubber layer is exposed in a region of at least 20% of an upper surface toward the inside of the block from the first edge and a region of at least 60% of a front surface in a radially inward direction from the first edge; the first rubber layer occupies at least 20% and at most 80% of the volume of the block; and a glass transition temperature Tg of the first rubber composition is at most equal to -20°C and the glass transition temperature Tg of the second rubber composition is greater than -20°C.
