该测试旨在评估乘用车、轻型卡车和多用途车辆使用的车轮和轮胎组件的正面抗冲击性。该测试特别与大多数车辆制造商进行的车辆坑洼测试相关。范围已经扩大，允许使用可以倾斜以优先撞击内侧和外侧车轮凸缘的撞针。仅对于外侧轮辋法兰的侧面碰撞，请参考SAE J175。本SAE推荐规程提供了测试车轮或轮胎的程序以及测试失效标准。车辆的特定测试需要来自该车辆上的坑洞测试的输入，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.
