摘要 PROBLEM TO BE SOLVED: To improve noise performance of a tire while improving maneuverability of the tire.SOLUTION: At least one land part 20 includes: an outer wall surface 30 positioned in a vehicle outside; an inner wall surface 31 positioned in a vehicle inside; a tread 32 in a tire diameter direction outside; an outer edge 33 of the tread 32 contacting the outer wall surface 30; and an inner edge 34 of the tread 32 contacting the inner wall surface 31. The tread 32 is formed in a protruding shape smoothly curved between the outer edge 33 and the inner edge 34 in a cross section of the land part 20 in a tire width direction, and having an apex 43 mostly protruding to a tire diameter direction outside. When a distance in the tire diameter direction between the apex 43 and the outer edge 33 is made to Do, and a distance in the tire diameter direction between the apex 43 and the inner edge 34 is made to Di, a relation is Do<Di. The apex 43 is positioned in the inner edge 34 side than a center P in the tire width direction of the land part 20.
