A tire (10) comprises a crown reinforcement (16) comprising a working reinforcement (20) comprising a radially outermost working ply (26) and a hooping reinforcement (22) comprising a plurality of filamentous fabric hooping elements (220), the plurality of filamentous fabric hooping elements (220) being arranged between the working ply (26) and the hooping reinforcement (22). The plurality of filamentous fabric hoop elements (220) are helically wound radially around the working reinforcement (20) and connected to each other by one or more filamentous weft elements (42). In an axial central portion (P0) of the crown (12), an average radial distance E2 between the filamentous fabric hooping element (220) and the metal wire working reinforcement (260) satisfies E2 < = 0.40 mm. Each filamentous weft element (42) comprises a plurality of fabric monofilaments and/or a plurality of fabric fibers selected from the group consisting of synthetic organic polymer monofilaments and fibers, synthetic inorganic polymer monofilaments and fibers, and combinations of these monofilaments and fibers.

    轮胎(10)包括胎冠增强件(16),所述胎冠增强件(16)包括工作增强件(20)和环箍增强件(22),所述工作增强件(20)包括径向最外工作帘布层(26),所述环箍增强件(22)包括多个丝状织物环箍元件(220),所述多个丝状织物环箍元件(220)围绕工作增强件(20)沿径向螺旋缠绕并通过一个或多个丝状纬向元件(42)彼此连接。在胎冠(12)的轴向中心部分(P0)中,丝状织物环箍元件(220)和金属丝线工作增强件(260)之间的平均径向距离E2满足E2≤0.40mm。每个丝状纬向元件(42)包括多个织物单丝和/或多个织物纤维,所述多个织物单丝和/或多个织物纤维选自合成有机聚合物单丝和纤维、合成无机聚合物单丝和纤维以及这些单丝和纤维的组合。
