摘　　要：介绍公交车专用275/70R22.5 AU609高性能子午线轮胎的研发。产品特点为:带束层采用3+8×0.33ST超高强度钢丝帘线;胎体采用无焊点钢丝帘线;增加胎圈锦纶包布;加强胎侧结构和胎侧磨耗标识;新增防刮擦设计;胎面采用3条主花纹沟设计、曲折花纹沟底和全新的3D互锁钢片技术;优化设计胶料配方。成品性能试验结果表明,轮胎的耐久性能良好,滚动阻力系数为6.4 N·kN^(-1),压穿强度和耐磨性能大幅提高,路试轮胎耐久性能和可翻新性好,产品得到客户认可。The development of 275/70R22. 5 AU609 high performance radial tire for bus was introduced. The product features were as follows:3+8×0. 33ST super high tenacity steel cord was applied in the belt,steel cord without solder joint was adopted in the carcass,nylon wrap was added for the bead,the identification for the sidewall structure reinforcement and sidewall wear was put on,a new scratch resistant design was adopted,a design of three main grooves with zigzag groove bottom and new 3D interlocking steel sheet technology was used for the tread,and the compound formula was optimized. The performance test results of the finished product showed that the durability of the tire was good,the rolling resistance coefficient was 6. 4 N·kN-1,the puncture strength and wear resistance were greatly improved,and the durability and retreading performance of the actual road tire was good. The products had been recognized by customers.
