The present invention relates to a pneumatic tire formed from a rubber composition, the rubber composition containing a first polymer and a second polymer, the first polymer being a hydrogenated copolymer that contains a structural unit derived from an aromatic vinyl compound and a structural unit derived from a conjugated diene compound and has a degree of hydrogenation of the conjugated diene portion of 75 mol% or more, the second polymer having a double bond-containing diene content of 20% by mass or less and a weight average molecular weight of 200,000 to 2,000,000.",
