要約
(EN)

Provided are pneumatic tires having good processability and achieving a balanced improvement in wet-grip performance, fuel economy, abrasion resistance, flex fatigue resistance, and durability. The invention relates to a pneumatic tire including at least one selected from the group consisting of a tread, a sidewall, and a tire internal component, the at least one being formed from a rubber composition containing carbon black, silica, and an emulsion-polymerized rubber that has an acetone extractable content of at most 2.5% by mass when determined by an acetone extraction method; or a pneumatic tire including at least one selected from the group consisting of a tread, a sidewall, and a tire internal component, the at least one being formed from a rubber composition containing carbon black, silica, and an emulsion-polymerized rubber that has a soap content of at most 2.5% by mass and an organic acid content of at most 2.5% by mass.
