PROBLEM TO BE SOLVED: To suppress increase of strain while making a ply end of a carcass ply approach to a bead part side.SOLUTION: A tire 10 comprises a pair of bead cores 18 and at least one carcass ply 15. The carcass ply 15 comprises ply body parts 16 and ply folding back parts 17. The ply folding back parts 17 are continuous to the ply body parts 16, are folded from inside to outside of the bead cores 18 in a tire width direction, and extend to ply folding back ends 19, respectively. The bead cores 18 have a first core 20 and a second core 21. The ply folding back ends 19 are sandwiched by the first core 20 and the second core 21 from a direction inclined to the tire width direction. An interval between the first core 20 and the second core 21 is 150% or more and 200% or less of diameter of a ply cord which forms the carcass ply 15.SELECTED DRAWING: Figure 1 |
