1.1 本规范涵盖P225/60R16 97S径向低胎面深度标准参考试验轮胎的一般要求。本规范涵盖的轮胎主要用作处于磨损状态的轮胎的湿制动牵引力评估的参考轮胎，但也可用于其他评估。 1.2 本规范提供了16轮辋直径代码标准轮胎设计和结构、标准尺寸，并规定了储存条件。 1.3 以英寸-磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers the general requirements for the P225/60R16 97S radial low tread depth standard reference test tire. The tire covered by this specification is primarily for use as a reference tire for wet braking traction evaluations for tires in a worn state but may also be used for other evaluations. 1.2 This specification provides a 16 rim diameter code standard tire design and construction, standard dimensions, and specifies the conditions of storage. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
