TIRE AND TIRE-VEHICLE COMBINATION

An outer surface TS of a tire 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 CR of a first crown arc to a radius CR 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 located in a zone from an equator to a first tread reference end TE is larger than a total groove volume of a second circumferential groove located in a zone from the equator to a second tread reference end TE
