PROBLEM TO BE SOLVED: To provide a tire effectively improved in abrasion resistance, particularly the uneven abrasion resistance of a block while securing wet performance.SOLUTION: A tire includes: a plurality of peripheral grooves extending in the tire peripheral direction; a plurality of width grooves extending in the tire width direction; and a block which is formed with the plurality of peripheral grooves and the plurality of width grooves. A peripheral direction sidewall angle formed of one of the peripheral direction sidewall surfaces formed on the block by the peripheral direction grooves and a tread is changed to be obtuse at one end in the tire peripheral direction of the block while being acute at the other end in the tire peripheral direction of the block. A width direction sidewall angle formed of the width direction sidewall surface formed on the block by the other width direction grooves and the tread is changed from an acute angle to an obtuse angle as approaching the peripheral direction sidewall surface. A bottom raised portion raised to the outside in the tire diameter direction is formed on the bottom of width direction grooves. |
