该试验旨在评估用于乘用车、轻型卡车和多用途车辆的车轮和轮胎总成的正面冲击阻力。该试验与大多数车辆制造商进行的车辆坑洞试验特别相关。该范围已经扩大，允许使用可以倾斜的撞销，以优先冲击内侧和外侧车轮法兰。关于外侧轮辋凸缘的侧面碰撞，请参考SAE J175。本SAE推荐实施规程提供了测试车轮或轮胎的程序和测试失败标准。车辆的特定测试需要从该车辆的坑洞测试中输入，以确定该测试中使用的撞针的跌落高度。

The test is designed to evaluate the frontal impact resistance of wheel and tire assemblies used with passenger cars, light trucks and multi-purpose vehicles. The test is specifically related to vehicle pothole tests that are undertaken by most vehicle manufacturers. The scope has been expanded to allow the use of a striker that can be angled to preferentially impact the inboard and outboard wheel flange. For side impact of the outboard rim flange only, please refer to SAE J175. This SAE Recommended Practice provides a procedure to test a wheel or a tire and the test failure criteria. The specific test for a vehicle requires input from a pothole test on that vehicle to establish the drop height of the striker used in this test.
