PROBLEM TO BE SOLVED: To provide a pneumatic tire which can improve durability performance.SOLUTION: A pneumatic tire 1 includes a pair of bead cores 11, 11, a carcass layer 13 hung over between the pair of bead cores 11, 11 and a belt layer 14 which is constituted by stacking at least four sheets of belt ply 141 to 144 made by covering a steel belt cord with coat rubber and is arranged on the outside in the tire diameter direction of the carcass layer 13. Further, an inter-cord distance Ga between the outermost layer belt ply (fourth belt 144) and an adjacent belt ply (third belt 143) has the relation of 0.80≤Ga/&phgr;max≤1.80 with respect to the maximum value &phgr;max of the outer diameters &phgr;4, &phgr;3 of belt cords 1441, 1431 in the outermost layer belt ply 144 and the adjacent belt ply 143. |
