The invention relates to the technical field of tires, and discloses a high-durability tire which is characterized in that a tire body turn-up end part and a chafer end part are respectively provided with a covering piece for covering the corresponding tire body turn-up end part and the chafer end part, and the outer sides of the tire body turn-up end part and the chafer end part are respectively provided with a rubber supporting layer. According to the covering part, the bonding force between the tire body turn-up end and the adjacent rubber layer and between the tire chafer end and the adjacent rubber layer can be increased, separation is restrained, the durability of the tire is improved, the service life of the tire is prolonged, heat accumulated at the tire body rolling end can be rapidly dissipated, and damage to the tire body rolling end due to heat generation is reduced; the arranged rubber supporting layer can be further matched with the covering part to transmit heat to the outside of the tire bead, the heat dissipation performance of the tire bead is further improved, fatigue damage of the tire bead is reduced, and the service life of the tire bead is prolonged; compared with the prior art, the design is more reasonable, and the actual use requirement can be better met.
本发明涉及轮胎技术领域,公开了一种高耐久性轮胎,胎体反包端部和胎圈包布端部均设有覆盖相应的胎体反包端部和胎圈包布端部的覆盖件,胎体反包端部和胎圈包布端部的外侧设有橡胶支撑层。本发明的覆盖件,既能增加胎体反包端部和胎圈包布端部与临近橡胶层的粘结力,抑制分离,提高轮胎的耐久性和使用寿命,又能使胎体卷起端部聚集的热量快速消散,降低胎体卷起端部因生热而导致的破坏;设置的橡胶支撑层能进一步配合覆盖件将热量传递到胎圈外部,进一步改善胎圈散热性能,降低胎圈的疲劳损伤,提高胎圈的使用寿命;相比于现有技术,本发明的设计更合理,可以更好地满足实际使用的需求。
