Tire

A tire comprising a plurality of land portions formed on a tread portion by a plurality of circumferential grooves extending in a tire circumferential direction, a mounting direction of the tire with respect to a vehicle being designated, wherein:

• at least one of the land portions includes an outer wall surface positioned on a vehicle outer side, an inner wall surface positioned on a vehicle inner side, a tread surface on an outer side in a tire radial direction, an outer edge of the tread surface in contact with the outer wall surface, and an inner edge of the tread surface in contact with the inner wall surface;
• the tread surface of the land portion is formed in a convex shape which is smoothly curved between the outer edge and the inner edge and which has a top portion most protruded outward in the tire radial direction, in a cross section of the land portion in a tire width direction;
• a relationship of Do<Di is satisfied when a distance between the top portion of the tread surface and the outer edge in the tire radial direction is donated as Do, and a distance between the top portion of the tread surface and the inner edge in the tire radial direction is donated as Di;
• and
• the top portion of the tread surface is positioned closer to the inner edge side than a center of the land portion in the tire width direction.
