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.

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.

This terminology aims to encompass all terms and definitions pertaining to the road performance of pneumatic tires designed for over-the-highway use, such as passenger car, light truck, truck and bus, and motorcycle tires. Not included are terms specific to the performance of agricultural, aircraft, industrial, and other off-highway tires. However, many terms contained in this document also apply to non-highway tires.

This Information Report presents background and rationale for SAE Recommended Practice J1106, Laboratory Testing Machine and Procedures for Measuring the Steady Force and Moment Properties of Passenger Car Tires. The purpose of SAE J1106 is to define standards for equipment design and test procedures so that data from different laboratories can be directly compared. Whereas such standardization is not a requirement for testing associated with tire development, it is necessary in the context of vehicle design and tire selection problems. The basic approach employed in developing SAE J1106 was to consolidate and document existing technology as embodied in equipment and procedures currently employed for routine tire evaluations. Equipment and procedures whose current use is restricted to research applications were not considered. Research experience is discussed in this Information Report, however, to the extent deemed necessary to provide background and rationale for SAE J1106.

This Recommended Practice describes some basic design requirements and operational procedures associated with equipment for laboratory measurement of tire force and moment properties of the full range of passenger car tires. These properties must be known to establish the tire's contribution to vehicle dynamic performance. Many factors influence laboratory tire force and moment measurements. This Recommended Practice was compiled as a guide for equipment design and test operation so that data from different laboratories can be directly compared and applied to vehicle design and tire selection problems. It is recognized that laboratory measurements define performance in a controlled and idealized situation that may not correspond to conditions encountered in a vehicle's operating environment. Several decades of testing experience in different laboratories indicates, however, that these tests can provide a very useful bench mark for evaluation of tire performance.

This document establishes best practices to measure vehicle stopping distance on dry asphalt in a straight path of travel intended for the purpose of publishing stopping distance by manufacturers and media organizations. It is recommended that the test method within be adopted for all vehicles less than 10 000 lb (4536 kg) GVWR. This procedure is typically used with initial speeds of 100 km/h and 60 mph, but other speeds may be used.

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.

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.

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.

This SAE Recommended Practice applies to the laboratory measurement of rolling resistance of pneumatic passenger car, light truck, and highway truck and bus tires. The procedure applies only to the steady-state operation of free-rolling tires at zero slip and inclination angles; it includes the following three basic methods: Force Method--Measures the reaction force at the tire spindle and converts it to rolling resistance. Torque Method--Measures the torque input to the test machine and converts it to rolling resistance. Power Method--Measures the power input to the test machine and converts it to rolling resistance.

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.
