The invention relates to the technical field of tire manufacturing, and discloses a low-rolling-resistance truck radial tire which comprises a tread, a sidewall, a belted layer, a tire body, a steel wire ring and steel wire wrapping cloth, the outer contour of the tread is of an arc-shaped structure on a tire interface, the arc length of the tread is L, the arc length L adopts the design of two sections of tangent arcs, and the arc length L is larger than the arc length L; the tread is provided with three pattern grooves which divide the tread into four same pattern blocks, the three pattern grooves are composed of two conventional open type longitudinal grooves and a Y-shaped longitudinal groove in the longitudinal direction, and the Y-shaped longitudinal groove is located between the two open type longitudinal grooves. According to the truck radial tire with the low rolling resistance, by optimizing the structural design, the pattern design and the formula design of the tire, the tire has the ultra-low rolling resistance performance, and meanwhile eccentric wear and different wear can be effectively reduced.

    本发明涉及轮胎制造技术领域,且公开了一种低滚阻的载重子午线轮胎,包括胎面、胎侧、带束层、胎体、钢丝圈、钢丝包布,所述胎面外轮廓在轮胎界面上呈弧形结构,所述胎面的弧长为L,所述弧长L采用两段相切的圆弧设计,所述胎面设置有三道花纹沟将胎面分成四个相同的花纹块,三道所述花纹沟在纵向上由两道常规的开放式纵沟和一道Y型纵沟组成,所述Y型纵沟位于两道开放式纵沟之间。该低滚阻的载重子午线轮胎,通过从轮胎结构设计、花纹设计和配方设计进行优化,实现轮胎具有超低滚阻性能,同时可以有效降低偏磨和异磨发生。
