Abstract

An object of the present disclosure is to provide a tire having improved overall performance of an initial grip performance and a peak grip performance on a dry road surface. Provided is a tire comprising a tread part, the tread part having two or more circumferential grooves extending continuously in a tire circumferential direction, a pair of shoulder land parts partitioned by the circumferential grooves and grounding ends, a center land part located between the pair of shoulder land parts, and a width direction groove, wherein a land ratio R on a grounding surface of the tread part is 0.50 to 0.80, wherein the tread part has at least one rubber layer consisting of a rubber composition comprising a rubber component, and wherein an average value tan δA of a loss tangent tan δ of the rubber composition at -15°C to 20°C, measured under a condition of a frequency of 10 Hz, an initial strain of 0.1%, and a dynamic strain amplitude of ± 0.25%, is 0.40 to 0.60.
