[Problem] To provide a pneumatic tire excellent in fuel efficiency, handling stability, and riding comfort in a well-balanced manner. A pneumatic tire having a tire member made of a rubber composition having physical properties after vulcanization satisfying the following specific values. tan δ ≦ 0.11 (1) 1.10 ≦ (E * a / E * b) ≦ 1.53 (2) 0.072 ≦ (E * a / HS) ≦ 0.140 (3) (tan δ is Tan δ when measuring viscoelasticity at 10% initial strain, 1% dynamic strain and 50 ° C .; E * a is a tire when measuring viscoelasticity at 10% initial strain, 1% dynamic strain and 50 ° C. The complex elastic modulus E * a; E * b in the circumferential direction is the complex elastic modulus E * in the direction orthogonal to the tire circumferential direction when viscoelasticity measurement is performed at 10% initial strain, 1% dynamic strain, and 50 ° C. b; HS is the hardness at 50 ° C. (HS) measured according to JIS K6253-1. [Selection figure] None |
