本SAE推荐实施规程定义了在雪地中评估动态乘用车和轻型卡车轮胎行驶牵引力的最著名技术。典型驾驶员会遇到许多雪况，但本推荐规程中没有具体说明。本推荐规程中的动态驾驶牵引力是在温度、积雪压实度和深度（通常称为“测试窗口”）的狭窄可控范围内进行的，以将测试的可变性降至最低。轮胎排名可能因其他类型的冰雪条件而异。

This SAE Recommended Practice defines the best known techniques for evaluating dynamic passenger car and light truck tire driving traction in snow. There are many snow conditions which a typical driver will encounter that are not specifically addressed in this Recommended Practice. Dynamic driving traction in this Recommended Practice is under a narrow, controlled range of conditions of temperature, snow compaction and depth (commonly called the 'Test Window') to minimize test variability. Tire rankings may differ on other types of snow and ice conditions.
