A radial tire (21) includes a pair of sidewall portions (27) and a pair of bead portions (23). The tire (21) further has: a carcass reinforcement ply (29) comprising ply turn-ups (33), each ply turn-up comprising a radially outward ply end (35); and a heel reinforcement layer (37) disposed at each ply turn-up, the heel reinforcement layer (37) having a radially outward heel reinforcement layer end (39). The profile of the axially outer surface of the sidewall portion is a distance G from the carcass reinforcement ply from an axially outermost point of the axially outer surface (43) up to a point A and connects the axially outer surface (43) of the bead portion at a point B. An axially outer surface of the sidewall portion follows a first curve extending from point A and having a center of curvature located axially outward of the carcass reinforcement ply, and a second curve connecting point B and having a center of curvature located axially inward of the axially outer surface of the tire.
公开了一种子午线轮胎(21),其包括一对侧壁部分(27)和一对胎圈部分(23)。轮胎(21)进一步具有:胎体增强帘布层(29),其包括帘布层反包部(33),每个帘布层反包部包括径向向外的帘布层端部(35);以及设置在每个帘布层反包部处的胎跟加强层(37),其具有径向向外的胎跟加强层端部(39)。侧壁部分的轴向外表面的轮廓,从轴向外表面(43)的轴向最外点直到点A距胎体增强帘布层为距离G,并在点B处连接胎圈部分的轴向外表面(43)。侧壁部分的轴向外表面遵循从点A延伸并且具有位于胎体增强帘布层的轴向向外的曲率中心的第一曲线,以及连接点B并具有位于轮胎的轴向外表面的轴向向内的曲率中心的第二曲线。
