| 中文摘要: |
| 研究结构设计对225/45RF18 95W XL自体支撑型缺气保用轮胎零气压耐久性能的影响。结果表明：与单层胎体结构相比，双层胎体结构可以提高轮胎的零气压耐久性能，但轮胎质量较大，可用于大规格轮胎；圈部增强层有利于提高轮胎的零气压耐久性能，为本研究最优设计方案。 |
| 英文摘要: |
| The influence of structural design on the zero-pressure durability of 225/45RF18 95W XL self-supported run-flat tire was studied. The results showed that compared with single-layer carcass structure，double-layer carcass structure could improve the zero-pressure durability of the tire，but the tire would be heavier and could be used for large size tires.The bead reinforcement layer was beneficial to improve the zero-pressure durability of the tire，which was the best design in this study. |
