| 中文摘要: |
| 针对10R22.5规格的高海拔地区中长途客车用轮胎，分析提高其行驶里程的方法。结果表明：使用加宽的U形胎圈钢丝包布，并在钢丝包布外侧增加1层纤维包布加强层，同时使用复合胎圈填充胶、增大花纹深度、采用高耐磨胎面胶配方，轮胎的强度性能、耐久性能和耐磨性能均超过设计目标，实际路试中轮胎的行驶里程显著提高。 |
| 英文摘要: |
| For 10R22.5 specification tires for medium and long distance buses in high altitude areas，the methods to improve the driving distances were analyzed.The results showed that by using widened U-shaped bead wire wrap and adding a fiber wrap reinforcement layer on the outside of the wire wrap，as well as using composite bead filler，increasing pattern depth，and adopting a high wear resistant tread compound formula，the strength，durability and wear resistance of the tire exceeded the design goals，and the driving distance was significantly improved in actual road tests. |
