Abstract: A pneumatic tire which comprises a tread portion with a pair of tread edges, and a tire shoulder extending radially inwardly from one of the tread edges, provided with a curved surface comprising a convex curve, wherein, on a cylindrical surface centered on the tire axis and intersecting the curved surface, the convex curve swells axially outwards and has a curvature, and the curvature gradually diminishes towards the radially inside from the tread edge. It is possible that the tread portion is provided along the tread edges with a circumferentially extending rib and/or a circumferential row of blocks. In case of circumferential rib, the rib is provided with the curved surface comprising a plurality of the convex curves and a plurality of convex curves alternating therewith so that the curved surface is waved in the tire circumferential direction. In case of blocks in a circumferential row, it is preferable that each block is provided with the curved surface comprising at last one convex curve.

Abstract translation: 一种充气轮胎，其包括具有一对胎面边缘的胎面部分和从所述胎面边缘之一径向向内延伸的轮胎胎肩，所述轮胎胎肩设置有包括凸曲线的曲面，其中，在以轮胎轴线为中心的圆柱形表面上 并且与弯曲表面相交，凸曲线向外轴向膨胀并且具有曲率，并且曲率从胎面边缘朝径向向内逐渐减小。 可能的是，胎面部沿着胎面边缘设置有周向延伸的肋和/或周向排的块。 在周向肋的情况下，肋设置有包括多个凸曲线的弯曲表面和与其交替的多个凸曲线，使得曲面在轮胎周向上挥动。 在圆周行中的块的情况下，优选地，每个块具有包括最后一个凸曲线的曲面。
