The invention relates to a pneumatic tire (1) exhibiting improved behavior in relation to a standard pneumatic tire, without degradation of the rolling resistance. According to the invention, the pneumatic tire (1) comprises a reinforcing structure (7) comprising at least one reinforcing element (8) extending continuously in the inner annular cavity (6), from a crown interface (81), connected to aradially inner face of the crown (23), to a bead interface (82), connected to an axially inner face of the bead (41), the reinforcing structure (7) being distributed circumferentially around the circumference of the pneumatic tire, the axially outermost crown interface (81) of the reinforcing element (8) being positioned, in relation to the equatorial plane (XZ), at an axial distance A at the most equal to 0.45 times the axial width S, and the radially outermost bead interface (82) of the reinforcing element (8) being positioned, in relation to the radially innermost point (I) of the axiallyinner face of the bead (41), at a radial distance B at the most equal to 0.5 times the radial height H.
本发明涉及一种充气轮胎(1),其与标准充气轮胎相比具有改进的性能,而且不会使滚动阻力变差。根据本发明,充气轮胎(1)包括加强结构(7),所述加强结构(7)包括至少一个加强元件(8),所述加强元件(8)在内部环形腔体(6)中从与胎冠的径向内表面(23)连接的胎冠界面(81)连续延伸至与胎圈的轴向内表面(41)连接的胎圈界面(82);所述加强结构(7)沿周向分布在充气轮胎的圆周上;轴向最外加强元件(8)的胎冠界面(81)设置在相对于赤道平面(XZ)的轴向距离A处,所述轴向距离A至多等于轴向宽度S的0.45倍;径向最外加强元件(8)的胎圈界面(82)设置在相对于胎圈的轴向内表面(41)的径向最内点(I)而言的径向距离B处,所述径向距离B至多等于径向高度H的0.5倍。
