Abstract: A tire 1 includes a tread portion 2, and how the tire is to be oriented when mounted to a vehicle is specified for the tire. The tread portion 2 has an outer tread edge T1, an inner tread edge T2, a first crown main groove 4, a second crown main groove 5, and three land portions demarcated by the first crown main groove 4 and the second crown main groove 5. The land portions include an outer shoulder land portion 7 demarcated between the outer tread edge T1 and the first crown main groove 4. The outer shoulder land portion 7 has a largest width in a tire axial direction among the three land portions. The outer shoulder land portion 7 has an outer shoulder lateral groove 20 and an outer shoulder sipe 21.

Abstract: An outer surface TS of a tire 2 includes a tread surface T and a pair of side surfaces S. A plurality of arcs representing a contour of the tread surface T include a pair of crown arcs. A ratio of a radius CR1 of a first crown arc to a radius CR2 of a second crown arc is not less than 1.10 and not greater than 1.70. A total groove volume of a first circumferential groove 48 located in a zone from an equator to a first tread reference end TE1 is larger than a total groove volume of a second circumferential groove 50 located in a zone from the equator to a second tread reference end TE2.

Abstract: A tire has a tread portion including a first land portion including first and second circumferential edges and and a tread surface. On the first land portion, curved grooves are provided in a tire circumferential direction. Each curved groove extends from a first end on the first circumferential edge side, terminates at a second end within the first land portion, and includes first and second curved portions and on the first end and second end sides, respectively. The first curved portion is an arc curve with a radius of curvature having a center on the first circumferential edge side of the curved groove. The second curved portion is an arc curve with a radius of curvature having a center on the second circumferential edge side of the curved groove.
