Abstract
An object is to improve noise performance of a tire while enhancing movement performance thereof. At least one of the land portions (20) includes an outer wall surface (30) positioned on a vehicle outer side, an inner wall surface (31) positioned on a vehicle inner side, a tread surface (32) on an outer side in a tire radial direction, an outer edge (33) of the tread surface (32) in contact with the outer wall surface (30), and an inner edge (34) of the tread surface (32) in contact with the inner wall surface (31). The tread surface (32) is formed in a convex shape which is smoothly curved between the outer edge (33) and the inner edge (34) and which has a top portion (43) most protruded outward in the tire radial direction, in a cross section of the land portion (20) in a tire width direction. A relationship of Do <Di is satisfied when a distance between the top portion (43) and the outer edge (33) in the tire radial direction is denoted as Do, and a distance between the top portion (43) and the inner edge(34) in the tire radial direction is denoted as Di. The top portion (43) is positioned closer to the inner edge (34) side from a center (P) of the land portion (20) in the tire …
