ASTM F2869-24

1.1 This practice describes the procedure to create statistical prediction profilers which can be used to identify equivalent test severity conditions between a 1.707-m diameter laboratory roadwheel surface and a flat or highway surface for radial pneumatic light truck (LT) tires.

1.2 The prediction profilers are based on empirically developed linear regression models obtained from the analysis of a large database that was obtained from a comprehensive experimental test program for roadwheel and flat surface testing of typical radial light truck (LT) tires. See Section 7 and the research report2 for more details.

1.3 For this standard, SI units shall be used, except where indicated.
