Abstract

Provided is a pneumatic tire having well-improved fuel economy, rubber tensile strength, and abrasion resistance while maintaining adequate productivity. The present invention relates to a pneumatic tire formed from a rubber composition, the rubber composition containing a hydrogenated copolymer and a sulfur donor, the hydrogenated copolymer containing a structural unit derived from an aromatic vinyl compound and a structural unit derived from a conjugated diene compound and having a degree of hydrogenation of the conjugated diene portion of 75 mol % or more, the hydrogenated copolymer being present in an amount of 75% by mass or more based on 100% by mass of a rubber component in the rubber composition, the sulfur donor being present in an amount of 0.2 to 8 parts by mass per 100 parts by mass of the rubber component.
