Included is a tire which includes a tread including a rubber composition, the rubber composition containing rubber components including an isoprene-based rubber, a polybutadiene rubber, and a styrene-butadiene rubber, and fillers including silica and carbon black, the rubber composition satisfying the following relationships (1) to (3): (1) Isoprene-based rubber content > Styrene-butadiene rubber content; (2) Isoprene-based rubber content > Polybutadiene rubber content; and (3) Silica content ≥ Carbon black content, the tire satisfying the following relationships (4) and (5) with respect to the tan δ at 30°C of the rubber composition and the negative ratio N (%) of the tread: (4) tan δ at 30°C < 0.10; and (5) tan δ at 30°C x N < 4.0.",
