A pneumatic tire which has a base tread having sufficient rigidity, hardness and crack resistance, and sufficiently satisfies the compatibility among steering stability, ride quality and lowering of rolling resistance is provided. The pneumatic tire has a base tread comprising a rubber composition containing 0.5 to 10 parts by weight of a thermosetting resin based on 100 parts by weight of a diene rubber, wherein complex elastic modulus E* of the rubber composition measured at a measurement temperature of 60°C and dynamic strain of 1 % is 8 to 15 MPa, tan ´ is at most 0.15, and elongation at break EB of the rubber composition in a tensile test is at least 300 %.
The rubber composition further comprises carbon black having a nitrogen-specific area of 74 to 115 m 2 /g and the thermosetting resin is 0,5 to 2,5 parts by weight of a resorcin formaldehyde resin. |
