本SAE推荐实施规程的目的是为适应轮胎牵引装置（如轮胎链条）所需的车身、车架和车轮罩间隙制定指南，并提供根据其最大轮廓对这些装置进行分类的方法。此外，它使车辆制造商能够为每辆车指定适当的牵引装置。本报告适用于总重量不超过4535 kg（10 001 lb）的乘用车和轻型卡车。本文件不得解释为批准牵引装置在超过制造商规范的条件下运行，尽管出于测试目的可能需要短时间的此类运行。

The purpose of this SAE Recommended Practice is to set up a guide as to body, frame, and wheelhouse clearances required to accommodate tire traction devices (e.g., tire chains), and to provide a means of classifying these devices according to their maximum profile. In addition, it enables the vehicle manufacturer to specify the proper traction devices for each vehicle.This report is intended to apply to passenger cars and light trucks up to 4535 kg (10 001 lb) GVW. This document is not to be construed as approving traction device operation at conditions exceeding manufacturer's specifications, although short periods of such operations may be required for test purposes.
