<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire advantageous in improving quietness of a tire. Ž<P>SOLUTION: A bead core 14 is comprised by piling a plurality of layers 36 comprising: bead line rows 32; and a coat rubber 34 coating the bead line rows 32 in a tire radial direction. A bead line 30A comprising the bead line row 32 of at least a layer 36A positioned on the innermost diameter side in the tire radial direction among the plurality of layers 36, consists of an organic fiber cord with a vibrational absorption property (high viscosity). A bead line 30B comprising the bead line row 32 of at least a layer 36B positioned on the outermost diameter side in the tire radial direction among the plurality of layers 36, consists of a steel wire.
