PNEUMATIC TIRE

To provide a pneumatic tire in which collapse of a belt-like ply is prevented.SOLUTION: A pneumatic tire has a tread reinforcement layer 7. The tread reinforcement layer 7 is configured from a belt-like ply 9 which includes plural first ramps 15 and plural second ramps 16, and includes a lattice-like part 20 in which these ramps intersect leaving a space part 17. The first ramp 15 includes a first outside part 15a of which an angle with respect to a tire circumferential direction is gradually decreased toward one end 20e in a tire axial direction of the lattice-like part 20. The second ramp 16 includes a second outside part 16a of which an angle with respect to a tire circumferential direction is gradually decreased toward one end 20e. The first outside part 15a is continued to the second outside part 16a via a circumferential direction part 14 at one end 20e.SELECTED DRAWING: Figure 3 【課題】帯状プライの巻き崩れを防止した空気入りタイヤの提供。【解決手段】トレッド補強層７を有する空気入りタイヤである。トレッド補強層７は、複数の第１傾斜部１５と複数の第２傾斜部１６とを含み、かつ、これらが空間部１７を残して交差する格子状部２０を含む帯状プライ９で形成されている。第１傾斜部１５は、格子状部２０のタイヤ軸方向の一方の端２０ｅに向かってタイヤ周方向に対する角度が小さくなる第１外側部１５ａを含んでいる。第２傾斜部１６は、一方の端２０ｅに向かってタイヤ周方向に対する角度が小さくなる第２外側部１６ａを含んでいる。一方の端２０ｅにおいて、第１外側部１５ａは、第２外側部１６ａと周方向部１４を介して連なる。【選択図】図３
