| 中文摘要: |
| 使用4个规格、不同剩余花纹深度的磨损轮胎，通过实车测试研究磨损率对轮胎性能的影响。结果表明，随着磨损率增大，轮胎的滚动阻力系数呈先增大后减小的趋势，接地面积呈先减小后增大的趋势，干地制动性能呈先降低后提高的趋势但变化较小，湿地制动性能明显降低。 |
| 英文摘要: |
| By using four sizes of worn tires with different remaining pattern depths，the effect of the wear rate on tire performance was studied through actual vehicle testing.The results showed that with the increase of the wear rate，the rolling resistance coefficient of tire increased first and then decreased，contact area decreased first and then increased，dry braking performance decreased first and then increased，but changed little，and wet braking performance decreased significantly. |
