Standard Specification for 225/75R16C 116/114S M+S Radial Light Truck Standard Reference Test Tire
ABSTRACT
This specification covers the general requirements for the 225/75R16C 116/114S radial light truck (European light duty vehicle) standard reference test. In this specification, a 16.0 rim diameter code standard tire design and constructions, standard dimensions, and specific conditions of storage are provided. Tire used in this specification was used as a reference tire for braking traction, snow traction, and wear performance evaluation. The reference tire may also be used for testing pavement roughness, noise and other evaluations requiring a reference tire. Testing procedures for the tensile sheet, the 300% stress elongation, the elongation and the tire tread hardness shall be in accordance with the requirements detailed in the Practice D3182 and Test Methods D412 and D2240. Other specifies testing procedures are using of Type A durometer positioned in the centre of a pressure foot at a minimum of 6.0 mm, checking durometer operation and calibration, determining tired tread hardness and eliminating shock in the application of pressure foot.
SCOPE
1.1 This specification covers the general requirements for the 225/75R16C 116/114S radial light truck (or European light duty vehicle) 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 16.0 rim diameter code standard 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.
