摘要： At least one reinforcing rubber layer is provided in the part of each of two side wall portions which is on the outer side of a carcass layer. The outer circumferential end portions of the reinforcing rubber layers extend to positions in which they are disposed between the end portions of the innermost belt layer and the corresponding portions of the carcass layer, while the inner circumferential end portions of these rubber layers extend inward in the radial direction of the tire so as to overlap the bead fillers in positions on the outer sides of the end portions of the carcass layer in the widthwise direction of the tire. A 100% modulus at 100.degree. C. of the rubber constituting the reinforcing rubber layers is not higher than that of the rubber of the belt layers, and a dynamic elastic modulus at 20.degree. C. of the former rubber in the range of 10-40 MPa. The thickness of the portions of the reinforcing rubber layers which are between the edges of the innermost belt layer and the outer circumferential ends of the bead fillers is set securely to not less than 1.00 mm, and the thickness of the parts of the side wall portions which are on the tire outer sides of the reinforcing rubber layers also not less than 1.00 mm.
摘要翻译：在胎体层的外侧的两个侧壁部的每一个的部分设置有至少一个增强橡胶层。加强橡胶层的外周端部延伸到最内侧带束层的端部与胎体层的对应部分之间的位置，而这些橡胶层的内周端部向内延伸轮胎的径向方向，以便在轮胎的宽度方向上的胎体层的端部的外侧的位置处与胎圈填料重叠。构成加强橡胶层的橡胶在100℃下的100％模量不高于带束层橡胶的100％模量，前者橡胶的20℃下的动态弹性模量在10- 40MPa。在最内侧带层的边缘和胎圈填料的外周端之间的加强橡胶层的部分的厚度被牢固地设定在不小于1.00mm，并且侧壁部分的部分的厚度它们在加强橡胶层的轮胎外侧上也不小于1.00mm。
