The invention belongs to the technical field of tires and discloses a high-wear-resistance anti-puncture run-flat tire which comprises a tire main body, two side anti-puncture mechanisms are symmetrically arranged in an interlayer of the tire main body relative to the position where a tire shoulder and a tire side are connected, and a front anti-puncture area is formed by a gap between the two side anti-puncture mechanisms. An anti-pricking plate is arranged between the opposite tread rubber and the cap ply in the front anti-pricking area; the side face anti-pricking mechanism is arranged between the steel wire belt ply and the cap ply, the side face anti-pricking mechanism comprises an anti-pricking ring and a buffer rubber strip arranged on the anti-pricking ring, and the buffer rubber strip is arranged opposite to one side of the tire side and is fixedly connected with the anti-pricking ring through a metal suture. The anti-pricking plate is arranged at the position, opposite to the tire crown, in the interlayer of the tire body and used for preventing nails and the like from pricking the tire crown, meanwhile, the side face anti-pricking mechanism is arranged at the connecting position of the tire shoulder and the tire side, and the anti-pricking ring in the side face anti-pricking mechanism extends towards the tire shoulder and the tire side, so that when the tire shoulder and the tire side are impacted by hard objects, the tire shoulder and the tire side cannot prick the tire crown. And the tire main body is protected from being punctured to avoid the risk of tire burst.
本发明公开了属于轮胎技术领域的一种高耐磨防扎防爆轮胎,包括轮胎主体,轮胎主体夹层中相对胎肩与胎侧连接的位置对称设有两个侧面防扎机构,两个侧面防扎机构间隙构成正面防扎区,正面防扎区中相对胎面胶与冠带层之间设有防扎板;侧面防扎机构设于钢丝带束层与冠带层之间,侧面防扎机构包括防扎环及设于防扎环上的缓冲胶条,缓冲胶条相对胎侧一侧设置并通过金属缝线与防扎环连接固定。本发明通过在轮胎主体的夹层中相对胎冠的位置设有防扎板,用于防止钉子等扎破胎冠,同时在胎肩与胎侧连接的位置设有侧面防扎机构,通过侧面防扎机构中的防扎环向胎肩与胎侧方向延伸,使得胎肩与胎侧在受到硬物冲击时,保护轮胎主体不被扎穿避免爆胎的风险。
