Stepped sections (110) whereby the height of a block (100) gradually decreases towards the outside of the tire peripheral direction from the center of the block (100) are formed in a peripheral direction end section (160) of the block (100). The stepped sections (110) have a first stepped surface (111a) and a second stepped surface (121a). A stepped surface (110a) extends from an outside end section (140) towards an inside end section (150). |
