SAE J2014_202511

This SAE Standard applies to all combinations of pneumatic tires, wheels, or runflat devices (only as defined in SAE J2013) for military tactical wheeled vehicles only as defined in SAE J2013. This applies to original equipment and new replacement tires, retread tires, wheels, or runflat devices. This document describes tests and test methodology, which will be used to evaluate and measure tire/wheel/runflat system and changes in vehicle performance. All of the tests included in this document are not required for each tire/wheel/runflat assembly. The Government Tire Engineering Office and Program Office for the vehicle system have the responsibility for the selection of a specific test(s) to be used. The selected test(s) should be limited to that required to evaluate the tire/wheel/runflat system and changes in vehicle performance. Selected requirements of this specification shall be used as the basis for procurement of a tire, wheel, and/or runflat device for military tactical wheeled vehicles. During the latest Five-Year Review of this test procedure, a special effort was given to defining the ozone testing requirement. The other revisions identified during the Five-Year Review were released with the understanding that another revision would take place once the ozone requirement was determined. After much effort, the group converged upon ASTM D1149-Standard Test Method for Rubber Deterioration—Surface Ozone Cracking in a Chamber, Procedure B2: Static Strain Looped Specimen Test, in which rectangular specimens are mounted, in a looped fashion, causing a continuous strain on the looped portion. This is the only issue addressed in this Limited Scope Revision.
