PROBLEM TO BE SOLVED: To provide a pneumatic tire 2 achieving the improvement of durability.SOLUTION: In a tire 2, a filler 10 is laminated together with a clinch 8 at the axial direction outside of a carcass 14. A carcass ply 50 of the carcass 14 is folded back around a core 44 of a bead 12. A folding-back part 50a of the carcass ply 50 is located between the filler 10 and an apex 46. The clinch 8 has a maximum thickness Tcx which is measured along a normal line of an axial direction inner surface of the clinch 8. When the normal line for the thickness Tcx is defined as a first reference line L1, a ratio of a thickness Tf1 of the filler 10 measured along the first reference line L1 to the sum of the thickness Tf1 and the thickness Tcx is 0.1 or more and 0.6 or less. A percentage of a complex elastic modulus Ef of the filler 10 to a complex elastic modulus Ea of the apex 46 of the bead 12 is 70% or more and 125% or less.SELECTED DRAWING: Figure 2 |
