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.

Passenger Car and Light Truck Tire Dynamic Driving Traction in Snow

1985-10-01
HISTORICAL
J1466_198510
This SAE Recommended Practice defines the best known techniques for evaluating dynamic passenger car and light truck tire driving traction in snow. There are many snow conditions which a typical driver will encounter that are not specifically addressed in this Recommended Practice. Dynamic driving traction in this Recommended Practice is under a narrow, controlled range of conditions of temperature, snow compaction and depth (commonly called the 'Test Window') to minimize test variability. Tire rankings may differ on other types of snow and ice conditions.

Passenger and Light Truck Tire Traction Device Profile Determination and Classification

2000-09-12
HISTORICAL
J1232_200009
The purpose of this SAE Recommended Practice is to set up a guide as to body, frame, and wheelhouse clearances required to accommodate tire traction devices (e.g., tire chains), and to provide a means of classifying these devices according to their maximum profile. In addition, it enables the vehicle manufacturer to specify the proper traction devices for each vehicle. This report is intended to apply to passenger cars and light trucks up to 4535 kg (10 001 lb) GVW. This document is not to be construed as approving traction device operation at conditions exceeding manufacturer's specifications, although short periods of such operations may be required for test purposes.

Measurement of Passenger Car, Light Truck, and Highway Truck and Bus Tire Rolling Resistance

1984-06-01
HISTORICAL
J1270_198406
Basic Methods--The force, torque, and power methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, surface texture, and non-steady-state tire operations are excluded from the recommended practice because they are still in the research stage. Force Method--The chief advantage of the force method is that the only parasitic losses in the measurement are tire spindle bearing losses and aerodynamic losses associated with rotation of the tire and its wheel. The main disadvantage of this method is that the spindle force measured can contain a severe error caused by load misalignment and load-spindle force interaction ("crosstalk"). Elimination or compensation of these effects is necessary. A minor disadvantage is that the loaded radius of the tire must be measured in order to convert spindle force to rolling resistance.

Testing Machines for Measuring the Uniformity of Passenger Car and Light Truck Tires

CURRENT
J332_202003
The comfort and fatigue of vehicle passengers is 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 SAE Recommended Practice describes the design requirements for equipment to evaluate some of the characteristic excitations of passenger car and light truck tires which may cause disturbance 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 document also describes some broad aspects of the use of the equipment and lists precautionary measures that have arisen out of current experience. The intention underlying these recommendations is to establish a standardized measurement for use by the engineering community.
