Standard Specification for 245/70R19.5 136/134M Radial Truck Standard Reference Test Tire

ABSTRACT
This specification contains the general requirements for the 245/7OR19.5 136/134M radial truck standard reference test. Provided in this specification is a 19.5 rim diameter code standard truck design and construction, standard dimensions, and standard conditions of storage. A reference tire is covered in this specification for braking traction, snow traction, wear evaluations pavement roughness, noise and other forms of test requiring a reference tire. Test methods of the tensile sheet cure, the 300% stress elongation, and tensile sheet strength should be in accordance to the specified testing requirements presented in D3182, and D412. The testing procedure also includes using of Type A durometer centred at the presser foot at a minimum of 6.0 mm, chaking the durometer operation and the state of durometer calibration with rubber reference, determining tire tread hardness by four readings and quickly applying the presser foot to the tire tread without inducing shock.
SCOPE
1.1 This specification covers the general requirements for the 245/70R19.5 136/134M 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 19.5 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.
