Force and Moment Test Method

J1987_199801
This SAE Recommended Practice describes the determination of passenger car and light truck tire force and moment properties on a belt-type flat surface test machine. It is suitable for accurately determining five tire forces and moments in steady-state under free-rolling conditions as a function of slip angle and normal force which are incrementally changed in a given sequence.

This SAE Recommended Practice describes the determination of passenger car and light truck tire force and moment properties on a belt-type flat surface test machine. It is suitable for accurately determining five tire forces and moments in steady-state under free-rolling conditions as a function of slip angle and normal force which are incrementally changed in a given sequence. Heavy-duty tires are not considered in this document, because the measuring system would have force and moment ranges too large to meet sensitivity requirements for passenger and light truck tire force and moment measurements. A standard for heavy-duty truck tires would have many of the same features as this document, but the measuring system, would have to be extensively altered. Inclination angle combined with slip angle, pull forces, and any combination with spindle torque are not considered in this document. Standards needed for these topics will be considered separately.

Laboratory Testing Machines and Procedures for Measuring the Steady State Force and Moment Properties of Passenger Car Tires

HISTORICAL
J1107_197501
This Information Report presents background and rationale for SAE Recommended Practice J1106, Laboratory Testing Machine and Procedures for Measuring the Steady State Force and Moment Properties of Passenger Car Tires. The purpose of 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 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 J1106.

Laboratory Testing Machines for Measuring the Steady State Force And Moment Properties of Passenger Car Tires

CURRENT
J1106_201208
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 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. This recommended practice is based on types of equipment and procedures that are used in several laboratories for routine tire evaluation. This limits the scope of this recommended practice to equipment and methodology for measuring the steady state properties of free-rolling tires.

Light Vehicle Dry & Wet Stopping Distance Test Procedure

CURRENT
J2909_201806
This document establishes best practices to measure vehicle stopping distance on dry or wet asphalt in a straight path of travel intended for the purpose of publishing stopping distance by manufacturers and media organizations for vehicles with original equipment tires. It is recommended that the test method within be adopted for all vehicles less than 4536 kg (10000 pounds) GVWR. This procedure is typically used with initial speeds of 100 km/h and 60 mph, but other speeds may be used. Since tires play a significant role in stopping distance, this procedure covers tire types typically used as original equipment on new vehicles including all-season, summer, and all-terrain tires. This document may serve as a procedural guideline for all tire types, but the surface temperature correction formulas in this procedure were developed using all-season tires and may not be applicable to other tire types.

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

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.
