PASSENGER CAR TIRE PERFORMANCE REQUIREMENTS AND TEST PROCEDURES
1970-05-01
HISTORICAL
J918_197005
This SAE Standard provides minimum performance requirements and accompanying uniform laboratory test procedures for evaluating certain essential characteristics of new tires and newly retreaded tires intended for use on passenger cars. (The requirements published in this SAE Standard pertain to tire sizes currently used on American passenger cars and popular sizes used on imported passenger cars. For related information on tire sizes not listed, contact Society of Automotive Engineers, Inc., Detroit Branch Office, 18121 East Eight Mile Road, East Detroit, Michigan 48021.)

THE MEASUREMENT OF PASSENGER CAR TIRE ROLLING RESISTANCE
1984-06-01
HISTORICAL
J1270_198406
The force, torque, and power methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, and non-steady-state tire operations are excluded from the recommended practice because they are still in the research stage.

Laboratory Speed Test Procedure for Passenger Car Tires
2019-09-11
CURRENT
J1561_201909
This SAE Recommended Practice provides a method for testing the speed performance of passenger car tires under controlled conditions in the laboratory on a test wheel. This procedure applies to “standard load,” “extra load,” and “T-type high-pressure temporary-use spare” passenger tires.

PERFORMANCE REQUIREMENTS FOR SNAP-IN TUBELESS TIRE VALVES
1997-04-01
HISTORICAL
J1205_199704
This SAE Standard for snap-in tubeless tire valves was developed by the qualified engineers in the tire, valve, and automotive industries. It is based upon sound engineering principles, supported by laboratory testing and field experience, to establish acceptable levels of performance criteria for valves.

TESTING MACHINES FOR MEASURING THE UNIFORMITY OF PASSENGER CAR TIRES
1969-01-01
HISTORICAL
J332_196901
In recent years the comfort and fatigue of passengers in vehicles has become a major engineering consideration. Among the many factors involved are vibratory and auditory disturbances. Tires participate, among other elements of the vehicle, in exciting vibrations and noises. Furthermore, tires also may generate forces leading to lateral drift of the vehicle. This recommended practice describes the design requirements of equipment for evaluating some of the characteristic excitations of passenger tires causing disturbances in vehicles. The kinds of excitations treated result from nonuniformities in the structure of the tire and have their effect when a vehicle bearing the tire travels on a smooth road. This recommended practice also describes some broad aspects of the use of the equipment and lists precautionary measures that have arisen out of current experience.

Stepwise Coastdown Methodology for Measuring Tire Rolling Resistance
1999-06-01
HISTORICAL
J2452_199906
This SAE Recommended Practice is applicable to pneumatic Passenger Car “P” Type, Light Truck Metric, and Light Truck High Flotation tires, or similar tires approved by bodies other than Tire & Rim Association. The methodology is applicable within normal operating ranges of vertical load and inflation pressure, and for velocities between 115 km/h and 15 km/h (71 mph and 9 mph) during a relatively short duration event such as a coastdown. This procedure is applicable only to operation in the free-rolling mode at zero slip and camber angle for ambient temperatures between 20 °C and 28 °C (68 °F and 82 °F) and for surfaces with diameters of 1.2 m (48 in) diameter or greater. Details regarding the equipment, tires, and test methods used specifically for validation of this document are included in Appendix A. Two basic measurement methods covered by this document are as follows:
