The invention discloses a tire with a reinforcing structure. The tire comprises a tire body, a tire body reinforcing piece covering the outer side face of the tire body, and tire rubber covering the outer side face of the tire body reinforcing piece, a steel wire is wound in the tire body, and the tire is characterized in that a tire bead reinforcing structure is further arranged on the tire body,is arranged between the tire body reinforcing piece and the tire rubber and forms a reinforcing ring in the circumferential direction of the tire body; the centered positioning size L of the tire bead reinforcing structure meets the condition that the width W/2 of the tire body reinforcing part is equal to the length a-c of the tire bead reinforcing structure, wherein c is 0-50 mm; accurate positioning of tire bead reinforcement in the tire production process can be achieved, the stress of the tire bead part can be effectively dispersed, heat concentration of the tire bead part can be reduced, and the durability of the tire bead part under the overload condition of the tire is improved.
本发明公开了一种具有补强结构的轮胎,包括胎体,及覆盖在胎体外侧面的胎体增强件,及覆盖在胎体增强件外侧面的胎胶,所述胎体内缠绕有钢丝,其特征在于:所述胎体上还设置有胎圈补强结构,所述胎圈补强结构设置于胎体增强件与胎胶之间,并且沿胎体周向形成增强圈;所述胎圈补强结构居中定位尺寸L满足胎体增强件宽度W/2‑胎圈补强结构的长度尺寸a‑c,其中c为0‑50mm;可实现胎圈补强在轮胎生产过程中的精准定位,并能使胎圈部位的应力有效分散,可以减小胎圈部位的热量集中,提高轮胎在超负荷情况下胎圈部位的耐久性。
