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: This procedure is intended to provide a standard method for gathering data on a uniform basis, to be used for various purposes (for example, tire comparisons, determination of load or pressure effects, correlation with test results from fuel consumption tests, etc.). This document has been modified in order to provide a relevant single point test condition (Standard Reference Condition [SRC]) appropriate for high volume rolling resistance testing such as for regulatory or comparative purposes.
