Standard Specification for 315/70R22.5 154/150L Radial Truck Standard Reference Test Tire

ABSTRACT
This specification covers the general requirements for the 315/70R22.5 154/150L radial truck standard reference tire. Provided in this specification is a 22.5 rim diameter code standard truck tire design and construction, standard dimensions and standard condition of storage. This specified tire is primarily used as a reference tire for braking traction, snow traction, wear performance evaluations, pavement and noise evaluations and other tests that necessitate a reference tire. Testing methods for the tensile sheet cure, the stress at 300% elongation, the tensile strength shall be in accordance with the standards presented by D3182 and D412 respectively. The test methods also include checking of the durometer operation, checking the sate calibration of the durometer, determining the tire tread hardness by averaging four readings and applying the presser foot to the tire tread as rapidly as possible without shock.
SCOPE
1.1 This specification covers the general requirements for the 315/70R22.5 154/150L radial truck 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 22.5 rim diameter code standard truck tire design and construction, standard dimensions, and specifies the conditions of storage.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound 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.
