PROBLEM TO BE SOLVED: To provide a pneumatic tire 2 which is improved in eccentric wear resistance without impairing high-speed durability and steering stability.SOLUTION: In this tire 2, an inside layer 32 of a belt 12 is folded at an end of an outside layer 34, and a folded part 40 is located outside a radial direction of the outside layer 34. A profile of a tread face 22 includes a first reference circular arc located outside an axial direction, and a second reference circular arc located inside the axial direction of the first reference circular arc. A radius R2 of the second reference circular arc is larger than a radius R1 of the first reference circular arc. When setting a cross point between the first reference circular arc and the second reference circular arc as a reference point PC, the first reference circular arc and the second reference circular arc contact with each other at the reference point PC. The reference point PC is located inside the axial direction rather than an end PF of the folded part 40, and a ratio of an axial length from the end PF of the folded part 40 up to the reference point PC with respect to an axial width of the folded part 40 is not smaller than 20% and not larger than 35%.SELECTED DRAWING: Figure 1 |
