Abstract
This tire offers a well-balanced improvement in both dry grip performance and snow grip performance. [Solution] A tire comprising a tread portion and a belt layer disposed radially inward of the tread portion, wherein the tread portion is formed using a rubber composition containing styrene-butadiene rubber with a styrene content of 25% by mass or less as a rubber component, the belt layer includes metal cords as reinforcing cords, at least one layer is arranged such that the metal cords form an angle of 30 degrees or more with respect to the circumferential direction of the tire, and furthermore, the (St / AG) calculated based on the styrene content St (mass%) of the styrene-butadiene rubber and the angle AG (degrees) that the metal cords form with respect to the circumferential direction of the tire is less than 0.8.
