ASTM F1922-21

Standard Test Method for Tires, Pneumatic, Vehicular, Highway

SIGNIFICANCE AND USE
4.1 This test method establishes a standard procedure of comparative testing, for tire durability and treadwear, for the use of approving tires under the Administrator's Cooperative Approved Tire List (CATL) (2).
SCOPE
1.1 This test method covers comparative tire durability and treadwear. This test method covers commercially available, over the highway pneumatic tires, new and retreaded, both tube type and tubeless, for use on conventional passenger cars, station wagons, pursuit and emergency high speed and pursuit passenger vehicles, light trucks, medium to heavy truck, trailers, buses, and similar vehicles normally operated on public roads and highways. This test method also covers commercially available, special application light truck tires for operation on non-improved road surfaces.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 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.  
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

INTRODUCTION
This ASTM Standard has been developed to replace ASTM Provisional Standard PS 63-97. The
provisional standard was approved so that the U.S. military and other government agencies could
continue to purchase tested and qualified tires, until In 1998, the standards used for F1922 had been
approved. The provisional standard replaced the government’s specification ZZ-T-381, the Federal
Specification, Tires, Pneumatic, Vehicular, Highway, under the former Federal Tire Program. That
program was discontinued and is replaced by the U.S. Army Tank Automotive Command’s U.S.
Army’s Cooperative Tire Qualification Program (CTQP). While fulfilling the military’s commercial
and tactical needs, the CTQP will continue (CTQP), which replaced the Federal Tire Program, were
officially approved by ASTM. This ASTM Standard has been developed to serve federal, state and
local agencies that want to purchase qualified tires using this test method.
This test method is designed to be used in conjunction with the Administrator’s Approval and
