A tread for a tire includes a first circumferential main groove; a second circumferential main groove; a third circumferential main groove; and a fourth circumferential main groove. And the fourth circumferential main groove is provided with a stable structure for improving the rigidity of the tread. The stabilizing structure is axially offset from a centerline of the fourth circumferential main groove by a predetermined amount. The fourth circumferential main groove has an angled axially inner side wall, an angled axially outer side wall, and a curved bottom surface. A stabilizing structure extends radially inward from the curved bottom surface of the fourth circumferential main groove. 一种用于轮胎的胎面包括第一周向主沟槽；第二周向主沟槽；第三周向主沟槽；以及第四周向主沟槽。第四周向主沟槽有具有用于提高胎面刚度的稳定结构。稳定结构以预定量从第四周向主沟槽的中心线轴向偏移。第四周向主沟槽具有成角度的轴向内侧壁、成角度的轴向外侧壁和弯曲底部表面。稳定结构从第四周向主沟槽的弯曲底部表面径向向内延伸。
