Improved body ply shape for a tire

A tire is provided having a body ply that is displaced from the conventional equilibrium curve along the shoulder and upper side wall region of the tire in a manner that provides more uniform inflation growth along the crown region so as to reduce differences in rigidity between the center and shoulders of the tire, reduce load sensitivity, and/or decrease the propensity for cracking. A method for designing or constructing such a tire is also provided. 本发明提供种轮胎，其具有主体帘布层，所述主体帘布层沿着所述轮胎的胎肩和上部侧壁区域从常规平衡曲线位移，其位移的方式使得沿着胎冠区域提供更均匀的充气增大，以便减少轮胎的中心与胎肩之间的硬度差异，降低载荷敏感性和/或减少开裂倾向。本发明还提供种用于设计或构造此轮胎的方法。
