PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in aging resistance, wear resistance, chipping resistance and snow performance. A pneumatic tire contains 100 parts by mass of styrene-butadiene rubber having a weight average molecular weight of 800,000 or more and 30 to 50% by mass of butadiene rubber, and 100 to 150% by mass of silica. 10 to 20 parts by mass of low molecular weight butadiene rubber having a weight average molecular weight of 10,000 or more and 50,000 or less, 2 to 9 parts by mass of a thermoplastic resin, and a plasticizing agent. It is formed of a rubber composition for tires having a total of 40 to 70 parts by mass. [Selection diagram] Fig. 1
