A tire including a tread portion which contains a rubber composition containing rubber components including at least one isoprene-based rubber and at least one styrene-butadiene rubber, at least one silica having an average primary particle size of 15 nm or less, and at least one resin component, the rubber composition containing the isoprene-based rubber in an amount of 50% by mass or more based on 100% by mass of the rubber components and the silica in an amount of 30 parts by mass or more per 100 parts by mass of the rubber components, the tire satisfying the relationships (1) and (2): (1) PC ≥ 55.0% by mass; and (2) AE ≤ 5.0% by mass, wherein PC and AE represent the polymer content (% by mass) and acetone extractable content (% by mass), respectively, of the rubber composition.",
