According to one embodiment of the present invention, in order to improve lateral rigidity, there is provided a tire including a tread portion, a sidewall portion, and a bead portion (10) in which an outermost edge point (P) of the bead portion (10) is in contact with a rim (rim), the tire having a bead portion profile structure in which an X coordinate is 8.8 to 9.7 mm and a Y coordinate is 19.2 to 21.7 mm at an ETRTO (European Tire and Rim Technical Organization) standard reference point (Ref Resource Point) origin of coordinates (O).

    根据本发明的一实施例,为提高横向刚性,提供一种包括胎面部、侧壁部和胎圈部(10)的轮胎,其中所述胎圈部(10)的最外缘点(P)与轮辋(rim)接触,其ETRTO(欧洲轮胎和轮辋技术组织)标准参考点(Ref erence Point)坐标原点(O)处的X坐标为8.8至9.7mm,Y坐标为19.2至21.7mm的胎圈部轮廓结构的轮胎。
