ASTM F3611-22e1

Standard Specification for P225/60R16 97S Radial Low Tread Depth Standard Reference Test Tire

SCOPE
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.
