| 中文摘要: |
| 选用A，B和C公司生产的不同结构225/55ZRF17缺气保用轮胎为研究对象，进行轮胎断面剖析和结构分析，并进行静负荷试验，在标准负荷下，分别测量轮胎在标准充气压力和零充气压力下的下沉量，计算两种条件下轮胎下沉量的变化。结果表明，A，B和C公司生产的225/55ZRF17缺气保用轮胎下沉量的变化量分别为23.7，11.4和9.8 mm，C公司生产的缺气保用轮胎自身负荷能力最强。 |
| 英文摘要: |
| The 225/55ZRF17 run-flat tires with different structures produced by A，B and C companies were selected as the research objects，the section and structure of the tires were analyzed，the static load tests were carried out，the sinkage of tire was measured under standard inflating pressure and standard load，and zero inflating pressure and standard load respectively，and the sinkage variation of tires were calculated under two conditions.The results showed that the sinkage variations of 225/55ZRF17 run-flat tires produced by A，B and C companies were 23.7，11.4 and 9.8 mm respectively，and the run-flat tire produced by C company had the strongest self-loading capacity. |
