ASTM F724-23(Test Method)
Standard Test Method for Outdoor Evaluation of Tire Sidewall Component Cracking Resistance

SIGNIFICANCE AND USE
4.1 Test Methods D1149 and D1171 can be used to evaluate different aspects of fatigue and weather cracking resistance of sidewall component materials in the form of test specimens. The present method applies to complete tires that are subjected to actual weather exposure conditions. The present method is satisfactory for research and development purposes but is not applicable to regulatory statutes or purchase specifications until standard classifications of state of cracking, similar to those in Test Method D1171, can be established.
SCOPE
1.1 This test method covers procedures for evaluating passenger car tires for sidewall component integrity and cracking resistance, using an outdoor roadwheel.  
1.2 This test method evaluates the resistance of tire sidewalls to dynamic weathering, atmospheric ozone cracking, fatigue cracking, or openings of splices within, or of junctures between, sidewall components and cracking at molded sidewall elements.  
1.3 This test method is useful for evaluating tire black sidewalls, white, or other colored, sidewalls, and coverstrips.  
1.4 This test method is limited to comparative performance testing between a “control” sidewall component or assembly and one or more experimental alternatives that are built onto the same tire (“multisection”) or onto tires that are identical in all respects other than the sidewall variation.  
1.5 This test method is not applicable to evaluation of sidewall resistance to abrasion, as may be experienced in severe cornering or curb scuffing.  
1.6 The values stated in SI units are to be regarded as the standard.  
1.7 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. For specific precaution statements, see 5.2.  
1.8 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.

ASTM F870-23(Practice)
Standard Practice for Tread Footprints of Passenger Car Tires Groove Area Fraction and Dimensional Measurements

SIGNIFICANCE AND USE
5.1 The tread of a tire, the annular band that contacts the pavement, normally contains geometric tread pattern elements that are defined by grooves or voids. These are employed to confer appropriate traction properties to the tire, mainly on wet or snow-covered roads.  
5.2 One characteristic feature of tire tread patterns that is important for both traction and tire wear behavior is the percent or “fractional” groove area. The groove-area fraction is calculated with respect to the total or gross contact area.
SCOPE
1.1 This practice covers a technique for measuring the groove or void area of a tire tread pattern. The void area is measured on the inked impression of a tire tread statically loaded against heavyweight paper on a load platen.  
1.2 This procedure is intended to serve as a reference practice for measuring groove or tread pattern void areas in a tire-footprint impression. This technique is usable by any laboratory without special equipment although more sophisticated procedures are also commonly employed, such as optical or video camera processes.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

ASTM F1046-21(Guide)
Standard Guide for Preparing Artificially Worn Passenger and Light Truck Tires for Testing

SIGNIFICANCE AND USE
5.1 Tires having reduced groove depth are required in some tire tests to determine changes in performance as a tire wears in service. This guide describes the preparation of artificially worn tires. This guide is not meant to replace the development of worn tires through over-the-road travel when naturally worn tires are required. Further refinements of these techniques may be made with increased field experience.  
5.2 The amount of tread rubber to be removed (groove depth reduction) and the final surface texture are selected according to the requirements of a particular testing program.  
5.3 The type of test program determines the actual tolerance necessary on the final groove depth. For example, snow traction will require very close control of the final groove depth while vehicle handling tests can accommodate a wider tolerance on the final groove depth.
SCOPE
1.1 This guide outlines the preparation of artificially worn tires by tread rubber removal (cutting or grinding, or both) for subsequent performance testing. The purpose is to permit the preparation of test tires with a uniformly reduced tread groove depth and tread geometry that will yield repeatable test results while avoiding the time-consuming and costly over-the-road natural wearing of tires.  
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.

Standard Test Methods for Tire Performance Testing on Snow and Ice Surfaces

SIGNIFICANCE AND USE
5.1 These test methods describe techniques for assessing the performance characteristics of tires in a winter environment on snow and ice surfaces in a standardized manner. When only snow is referred to hereafter, it should be understood that ice is implied as appropriate.  
5.2 A series of maneuvers are conducted to characterize several aspects of the tire performance in snow, since a single maneuver is not sufficient to characterize all aspects of a tire's performance.
SCOPE
1.1 These test methods cover the evaluation of tire performance on snow and ice surfaces utilizing passenger car or light truck vehicles. Since the tires are evaluated as part of a tire/vehicle system, the conclusions reached may not be applicable to the same tires tested on a different vehicle.  
1.2 These test methods do not purport to identify every maneuver useful for determining tire performance in a winter environment.  
1.3 These test methods are not meant to evaluate vehicle performance. Allowing for the variability of test results with different vehicles, these procedures have been developed and selected to evaluate relative tire-snow performance.  
1.4 These test methods are suitable for research and development purposes, where tires are compared during a single series of tests. They may not be suitable for regulatory statutes or specification acceptance because the values obtained may not necessarily agree or correlate either in rank order or absolute traction performance level with those obtained under other environmental conditions on other surfaces or the same surface after additional use.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 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.

Standard Test Method for Bead Unseating of Tubeless Passenger and Light Truck Tires

SIGNIFICANCE AND USE
5.1 This test method establishes a standard procedure for the test and provides data that can be related to the force required to unseat the bead of a tire inflated with a specified pressure from the rim. This test method does not establish performance limits or tolerances for tire specifications.
SCOPE
1.1 This test method covers the static non-rolling laboratory method of determination of a tubeless tire’s resistance to bead unseating. The test requires the use of a standardized fixture and load machine. The test is conducted using a defined test pressure and method of determining the resultant force to unseat the tire from the rim.  
1.2 This test method is applicable for all passenger, light truck, and temporary spare tires.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
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.

ASTM F408-21(Test Method)
Standard Test Method for Tires for Wet Traction in Straight-Ahead Braking, Using a Towed Trailer

SIGNIFICANCE AND USE
5.1 The measured values are traction properties of tires obtained with the towed trailer described here on a given road surface, under given environmental conditions (ambient and road surface temperature, humidity, wind speed and direction, purity and film depth of water used to wet the road surface). They are carried out in accordance with the stated test procedures and reflect the performance of the total tire-vehicle environmental system. A change in any of these factors may change the measurements on a subsequent run of the test.  
5.2 These test methods are suitable for research and development purposes, where tires are compared during a single series of tests. They may not be suitable for regulatory statutes or specification acceptance, because the values obtained may not necessarily agree or correlate either in rank order or absolute traction performance level with those obtained on other road surfaces (or the same surface after additional wear), under other environmental conditions, or other towed trailers, or other test devices, or with results obtained with other test procedures.
SCOPE
1.1 This test method covers the measurement of braking traction of tires designed for passenger cars or light trucks. Such braking traction measurements are applicable to conditions wherein the vehicle is traveling straight ahead on a wet, paved surface.  
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.

1.1 This test method covers the determination of tire plunger energy required to completely penetrate the tread area of an inflated tire as indicated by a rupture, loss of inflation pressure, sudden drop in plunger force or bottom-out. The test requires utilization of a laboratory testing machine capable of slowly penetrating the tread surface of a tire with a plunger having a hemispherical end.  
1.2 This test method is applicable to pneumatic tires for vehicles normally used on the road.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.  
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.
