本SAE推荐实践定义了评估峰值和抱死车轮制动牵引力的最佳已知技术。它涵盖了轮胎制动牵引力的一个重要阶段，即潮湿或干燥的路面直行条件。然而，这只是整个轮胎牵引力领域的一小部分。随着为该复杂研究的其他阶段建立测试程序，将编写额外的补充程序。关于整个主题的讨论载于 附录B 这一推荐做法。

This SAE Recommended Practice defines the best known techniques for evaluating peak and locked wheel braking traction. It covers an important phase of tire braking traction, namely, the wet or dry pavement straight ahead conditions. However, this is but a small portion of the whole field of tire traction. As test procedures are established for other phases of this complex study, additional supplementary procedures will be written. A discussion of this entire subject is contained in Appendix B to this recommended practice.
