Wet or Dry Pavement Passenger Car Tire Peak and Locked Wheel Braking Traction

2018-02-15
CURRENT
J345_201802
This SAE Recommended Practice defines the best known techniques for evaluating peak and locked wheel braking traction. It covers an important phase of tire braking traction, namely, the wet or dry pavement straight ahead conditions. However, this is but a small portion of the whole field of tire traction. As test procedures are established for other phases of this complex study, additional supplementary procedures will be written. A discussion of this entire subject is contained in Appendix B to this recommended practice.

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.

ROLLING RESISTANCE MEASUREMENT PROCEDURE FOR PASSENGER CAR TIRES

1984-06-01
HISTORICAL
J1269_198406
This recommended practice applies to the laboratory measurement of rolling resistance of pneumatic passenger car tires designed primarily for normal highway service. 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:

RESIDUAL ALIGNING MOMENT TEST

1994-08-01
HISTORICAL
J1988_199408
This SAE Recommended Practice describes the determination of tire pull force properties for an uninclined tire (SAE J670e) on a laboratory flat surface tire force and moment machine. It is suitable for accurately determining pull forces and residual aligning moments for passenger and light-truck tires. These properties are important determinants of vehicle trim (See section 2.1.2). They describe steady-state, free-rolling pull effects ascribable to tires. The test method described in this document is suitable for comparative evaluation of tires for research and development purposes. The method is also suitable for modeling when followed carefully.
