Zusammenfassung:	PROBLEM TO BE SOLVED: To improve high-speed durability while securing excellent turning performance.SOLUTION: A band ply 7A is formed of a center band part 9 having a spirally-wound first band cord 9c made of steel and a shoulder bad part 10 having a spirally-wound second band cord 10c made of steel. A width W1 in a tire shaft direction of the center band part 9 is 20-30% of a width TW of a tread. An elongation L1of the band cord Pc in a 100 N load is smaller than an elongation L2of the second band cord 10c in a 100 N load.SELECTED DRAWING: Figure 1 【課題】優れた旋回性能を確保しながら高速耐久性能の向上を図る。【解決手段】バンドプライ７Ａは、螺旋状に巻回されるスチール製の第１バンドコード９ｃを有するセンタバンド部９と、螺旋状に巻回されるスチール製の第２バンドコード１０ｃを有するショルダバンド部１０とから形成される。センタバンド部９のタイヤ軸方向巾Ｗ１は、トレッド巾ＴＷの２０〜３０％。第１バンドコードＰｃの１００Ｎ荷重時におけるコードの伸びＬ１１００は、前記第２バンドコード１０ｃの１００Ｎ荷重時におけるコードの伸びＬ２１００より小である。【選択図】図１
