<p>Provided is a pneumatic tire having a tread that is capable of improving low fuel consumption, wet grip performance and wear resistance in a balanced manner. A pneumatic tire which has a tread that is produced using a rubber composition which contains a rubber component, silica (I) that has a nitrogen adsorption specific surface area of 100 m2/g or less, and silica (II) that has a nitrogen adsorption specific surface area of 180 m2/g or more. The content of a conjugated diene polymer (A) in 100% by mass of the rubber component is 5% by mass or more, said conjugated diene polymer (A) having a monomer unit based on a conjugated diene, a monomer unit based on a compound represented by formula (1) and a monomer unit based on a compound represented by formula (2), and at least one end of the copolymer being modified with a compound (G) described below or an alkoxysilane compound. The total content of the silica (I) and (II) relative to 100 parts by mass of the rubber component is 30-150 parts by mass, and the contents of the silica (I) and (II) satisfy the following formula. (content of silica (I)) × 0.2≤(content of silica (II))≤(content of silica (I)) × 6.5 Compound (G): at least one compound selected from the compound group consisting of compounds having an optionally substituted amino group and a carbonyl group and compounds having an optionally substituted amino group and a thiocarbonyl group. (In formulae (1) and (2), each of V1 and V2 represents a hydrocarbyl group having a polymerizable carbon-carbon double bond; S1 represents a substituted silyl group; and A2 represents a substituted amino group or a nitrogen-containing heterocyclic group.)</p> |
