The invention relates to a radial tyre (1) for heavy vehicles, in which the reinforcing elements of each hoop layer (331, 332, 333) form an angle with the circumferential direction of at most 5 DEG, the reinforcing elements of the transverse reinforcement layers (321, 322, 323) form an angle with the circumferential direction of between 10 DEG and 45 DEG, the radial tyre (1) being extendable, the structural elongation As of the polymer matrix in the rubberized state removed from the polymer matrix is at least equal to 0.5%, the total elongation at break At of the polymer matrix is at least equal to 3%, and the Young's modulus E of the polymer matrix under traction is at least equal to 150 GPa.

    本发明涉及一种用于重型车辆的子午线轮胎(1),其中每个环箍层(331、332、333)的增强元件与周向方向形成的角度至多等于5°,横向增强件层(321、322、323)的增强元件与周向方向形成的角度在10°至45°之间,是可延伸的,因此在从聚合物基质中取出的橡胶化状态下其结构伸长As至少等于0.5%,其总断裂伸长At至少等于3%,其在牵引下的杨氏模量E至少等于150GPa。
