A pneumatic tire includes 100 parts by mass of a rubber component including from 25-30 parts by mass of a diene rubber having a glass transition temperature of from −20° C. to −40° C., having a tertiary amine having an epoxy group as a modifying group, and a vinyl content from 35-45 mass %, 20-35 parts by mass of a diene rubber obtained by reacting a polyorganosiloxane to an active terminal of a diene-based polymer chain having the active terminal formed by making a polymer block A continuous with a polymer block B, the polymer block A including 80-95 mass % of isoprene and 5-20 mass % of an aromatic vinyl, having an active terminal, and having a weight average molecular weight from 500-15,000, the polymer block B including 1,3-butadiene and an aromatic vinyl and an active terminal, the vinyl content lower by from 5-25 mass % than that of the first conjugated diene polymer.
