1.1 本规范涵盖了测量轮胎路面摩擦力的专用光滑胎面标准轮胎的一般要求。该轮胎用于固定制动滑移连续摩擦测量设备，如跑道摩擦测试仪、表面摩擦测试仪或BV-11滑移机拖车。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。

1.1 This specification covers the general requirements for a special purpose, smooth-tread standard tire for measuring tire-pavement friction forces. The tire is utilized on fixed braking slip continuous friction measuring equipment such as the Runway Friction Tester, Surface Friction Tester, or BV-11 Skiddometer Trailer. 1.2 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.
