    Abstract: A steel cord having a 1×2 construction formed by twisting two wire strands together is used as a reinforcing layer of a pneumatic tire. The steel cord has a carbon content of from 0.60 to 0.75%, a strength in the tire of from 2,900 to 3,500 MPa, and a twisting angle of from 1.5 to 3.0°. Therefore, productivity can be enhanced while fatigue resistance of the steel cord used in the reinforcing layer is maintained. Additionally, fatigue resistance of the steel cord is further enhanced due to the average value of the forming factor of the steel cord of this tire being set to from 95 to 105% and the standard deviation σ being set to from 5 to 20%. As a result, tire durability can be enhanced.
