The invention relates to the technical field of tires, in particular to a light-duty truck tire with a steel wire tire body. A light truck tire with a steel wire tire body comprises a tire crown, a belted layer, the tire body, a lining, a sidewall and a tire bead, the tire bead comprises an upper apex, a lower apex and a steel wire ring, and the tire body bypasses the steel wire ring and is reversely wrapped on the outer side of the upper apex; a layer of isolation rubber sheet is pre-coated at the turn-up end point; a layer of seam allowance wrapping cloth is attached to the tire body after the tire body is reversely wrapped, the width of the seam allowance wrapping cloth ranges from 30 mm to 60 mm, the thickness of the seam allowance wrapping cloth ranges from 0.4 mm to 1.5 mm, the center position of the seam allowance wrapping cloth is roughly located at the reverse wrapping end point of the tire body, the upper end point of the seam allowance wrapping cloth keeps away from the upper apex end point by more than 10 mm, and the lower end point of the seam allowance wrapping cloth is not lower than the horizontal height where the point Q is located. The tire can meet the high bearing requirement of the market, and is low in production cost, low in rolling resistance and good in comfort and control performance. Industrial production of the steel wire carcass light truck tire is achieved, the production qualification rate is high, and market feedback is good.

    本发明涉及轮胎技术领域,尤其涉及一种钢丝胎体轻型载重汽车轮胎。一种钢丝胎体轻型载重汽车轮胎,该轮胎包括胎冠、带束层、胎体、内衬、胎侧和胎圈,胎圈包括上三角胶、下三角胶和钢丝圈,所述的胎体绕过钢丝圈反包至上三角胶的外侧;并在反包端点预包覆一层隔离胶片;胎体反包后再贴合一层子口包布,所述子口包布宽度在30mm‑60mm,厚度在0.4mm‑1.5mm,子口包布的中心位置大致位于胎体的反包端点,子口包布的上端点避开上三角胶端点10mm以上,下端点不低于Q点所在的水平高度。该轮胎可以满足市场的高承载需求,同时生产成本低、滚动阻力低、舒适性和操控性能良好。本发明实现钢丝胎体轻型载重汽车轮胎的工业化生产,并且生产合格率高,市场反馈良好。
