| 欧洲作为中国轮胎产品出口的重要地区，一般安全法规的出台将大大提升其产品准入的技术壁垒，增加轮胎研发成本和销售难度，将严重影响我国轮胎产品的出口。基于欧盟EU2019/2144法规和UN R117.03系列法规的修订方向，本文通过对UN R117.03修订的磨削程序作了深度解读并对8套不同品牌型号的自主品牌轮胎湿抓地性能做了摸底测试。本次摸底程序参照UN R117.02 Rev4法规新胎（附录5）及UN R117.03修订案磨损胎（附录 9）湿抓地测试程序，分别开展了车辆法和拖车法测试研究。结果表明：1.国内头部自主品牌的轮胎在磨损状态下的性能基本可以满足UN R117.03修订案的限值要求；2.轮胎在新胎状态和磨损状态下的湿地抓着性能无明显关联；3.同一样品轮胎使用拖车法和车辆法测试结果无明显关联。 |

| Europe is an important region for the export of Chinese tire products. The introduction of general safety regulations will significantly increase the technical barriers for product access, increase tire research and development costs, and make sales more difficult, which will seriously affect the export of Chinese tire products. Based on the revised direction of the European Union""s EU2019/2144 regulations and UN R117.03 regulations, this article conducts a deep interpretation of the grinding procedure based on the UN R117.03 revision and conducts a thorough test of the wet grip performance of eight different brands and models of independent brand tires. This test program refers to the wet grip test program of the new tire (Appendix 5) and the worn tire (Appendix 9) in the ECE R117 02 Rev4 regulations. The test research on the vehicle method and trailer method was carried out separately. The results show that: 1. The performance of the selected test tires in the worn state can basically meet the limit requirements of the UN R117.03 revision; 2. There is no significant correlation between the wet grip performance of tires in the new tire state and the worn state; 3. There is no significant correlation between the test results of the same sample tire using the vehicle method and the trailer method. |
