The invention discloses a cutting-resistant high-trafficability tire for gravel road conditions, which comprises a tire body, an extension type tire crown is arranged at the tail end of a tread of the tire body, a pattern groove of the tire body is provided with a stepped groove wall, and the tire side of the tire body is provided with an integrated edge convex type tire side embankment. The cutting-resistant high-trafficability tire is provided with an external tire tread. The bearing resistance of the tire is improved. The strength of the tire shoulder is improved. The cutting resistance and the punching resitance are improved. The tire provided by the invention is further provided with the stepped groove wall, compared with a common groove wall, the anti-cutting capability of the pattern groove can be improved, the mudstone self-cleaning capability of the tire can be improved, the tire provided by the invention is further provided with the integrated edge convex type tire sidewall decoration, the rigidity of the tire sidewall is improved, and the anti-puncture capability of the tire sidewall is improved. The tire is further provided with the two forward-wrapping polyester fiber cord fabric layers and the reverse-wrapping polyester fiber cord fabric layer, compared with a common two-layer reverse-wrapping design, the strength of polyester fibers of the tire body is higher, the supporting performance of the tire side and the overall rigidity of the tire side are improved, and the strength of a tire bead is higher.

    本发明公开了一种砾石路况抗切割高通过性轮胎,包括胎体,所述胎体行驶面末端设置有外延式胎冠,所述胎体的花纹沟设置有阶梯式沟壁,所述胎体的胎侧设置有一体棱凸式胎侧榜花,本发明设置有外延式胎冠,提高轮胎的抗负载能力,提高胎肩部位强度,增加抗切割能力和抗刺穿能力,本发明还设置有阶梯式沟壁,相比普通沟壁,可以提高花纹沟的抗切割能力,提高轮胎的泥石自清洁能力,本发明还设置有一体棱凸式胎侧榜花,提升胎侧刚性,提升胎侧的康刺扎能力,本发明还设置有两个正包聚酯纤维帘布层和一个反包聚酯纤维帘布层,相比普通两层反包设计,胎体的聚酯纤维强度更高,提高胎侧支撑性和胎侧整体刚性,胎圈强度更高。
