PROBLEM TO BE SOLVED: To provide a tire for effectively restraining partial wear of a block part arranged on a tread surface.SOLUTION: A tire includes land part rows formed by a plurality of main grooves of extending in the tire circumferential direction, a plurality of inclined grooves are formed in the land part row, and block parts are formed by being partitioned by the plurality of inclined grooves. The plurality of respective inclined grooves slantingly extend in the same direction of the tire circumferential direction toward the other end on the outside in the tire width direction from one end on the inside in the tire width direction. A main groove sidewall angle formed by one main groove sidewall surface formed in the block part by the main groove and a tread of grounding on a road surface of the block part, changes so as to become an acute angle on one end of the block part in the tire circumferential direction, and to become an obtuse angle on the other end of the block part in the tire circumferential direction, and an inclined groove sidewall angle formed by one inclined groove sidewall surface formed in the block part by the inclined groove and the tread, changes to an obtuse angle from an acute angle as approaching to one main groove sidewall surface. |
