A radial carcass tire for civil engineering vehicles comprises two tire bead cores (2) having a radial height Ht and a carcass reinforcement consisting of two layers. A first radially innermost layer (1) having a radial height Hdc is anchored in each bead to form a main portion (11) and a bead (12). The second tire body layer (3) is located on the outer side of the first layer (1) in the radial direction. The free end (A) of the bead (12) is located at a radial distance from the radially outermost point (21) of the bead core of the tire, which radial distance is at least equal to 1 and at most equal to 2 of Ht. From the end A of the bead (12) to a point B at 85% of the radial height Hdc, the distance between the carcass layers is at least equal to 2 times and at most equal to 11 times the diameter of the metal reinforcements of the first carcass layer (1).

    用于土木工程车辆的子午线胎体轮胎包括两个具有径向高度Ht的轮胎胎圈芯部(2)和由两个层构成的胎体增强件。具有径向高度Hdc的第一径向最内层(1)锚固在每个胎圈中以形成主要部分(11)和卷边(12)。第二胎体层(3)沿径向位于所述第一层(1)的外侧。卷边(12)的自由端部(A)位于距轮胎胎圈芯部的径向最外点(21)的一定径向距离处,该径向距离至少等于Ht的1倍且至多等于Ht的2倍。从卷边(12)的端部A到径向高度Hdc的85%处的点B,胎体层之间的距离至少等于第一胎体层(1)的金属增强体的直径的2倍且至多等于所述直径的11倍。
