PURPOSE:To realize a lightweight tire while securing the durability and the actual vehicle maneuvering stability of the tire. CONSTITUTION:By providing a pair constitution of divided plies 23a and 23b in the axial direction of a tire at a specific interval Wg, the first ply 23 in which a break 31 is formed along the circumferential direction has been composed, and by providing divided plies 25a and 25b at a specific interval Wn, the third ply 25 in which a break 33 is formed has been composed. In this case, the divided plies 23a and 23b, and the divided plies 25a and 25b are arranged at the positions symmetric to the equatorial surface 28, and at the same time, both the intervals Wg and Wn of setting the divided plies 23a and 23b, and the divided plies 25a and 25b, are made narrower than the width L in the tire axial direction in a belt ply 15a. |
