The invention discloses a low-rolling-resistance and high-abrasion truck radial tire, and relates to the technical field of tire design, the truck radial tire comprises a tire body, a tread, a tire body, a sidewall, a tire bead, a belted layer, a steel wire ring and apex, the relation of the outer contour of the tire body is h/D > = 1.2% and < = 5.2%, the radial height difference between the end point of the outer contour of the tread and the middle point of the outer contour of the tread is h, and the width of the tire body is 0.5 mm. The vertical distance from the widest end point position in the belted layer to the grounding contour is D, the relationship of the inner contour of the tire body is (Gs-h)/Gc is greater than or equal to 0.98 and less than or equal to 1.02, the vertical distance from the end point of the outer contour of the tread to the inner contour is Gs, and the vertical distance from the midpoint of the outer contour of the tread to the inner contour is Gc. The design scheme of the low-rolling-resistance and high-abrasion truck radial tire is obtained by starting from key design elements of the tire and considering the relation between the rolling resistance and the abrasion of the tire, more fuel oil can be saved, and the abrasion mileage is longer.

    本发明公开了一种低滚阻高磨耗载重子午线轮胎,涉及轮胎设计技术领域,包括轮胎本体、胎面、胎体、胎侧、胎圈、带束层、钢丝圈和三角胶,轮胎本体外轮廓的关系为h/D≥1.2%且≤5.2%,胎面外轮廓端点到胎面外轮廓中点的径向高度差为h,带束层中最宽端点位置距离接地轮廓的垂直距离为D,轮胎本体内轮廓的关系为(Gs‑h)/Gc≥0.98且≤1.02,胎面外轮廓端点到内轮廓的垂直距离为Gs,胎面外轮廓中点至内轮廓的垂直距离为Gc。本发明通过从轮胎的关键设计要素出发,兼顾轮胎的滚阻和磨耗的关系,从而得到低滚阻高磨耗载重子午线轮胎的设计方案,本发明可以节省更多燃油,并且磨耗里程更长。
