(Specification)Standard Specification for P225/60R16 97S Radial Standard Reference Test Tire
Standard Specification for P225/60R16 97S Radial Standard Reference Test Tire
SCOPE
1.1 This specification covers the general requirements for the P225/60R16 97S radial standard reference test tire. The tire covered by this specification is primarily for use as a reference tire for braking traction, snow traction, and wear performance evaluations, but may also be used for other evaluations, such as pavement roughness, noise, or other tests that require a reference tire.
1.1.1 Other standard reference test tires are also used for these purposes and are referenced in Section 2.
1.2 This specification provides a rim code diameter of 16 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 and health practices and determine the applicability of regulatory limitations prior to use.
