1 Scope This document specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks and buses. This document is not applicable to tyres intended for temporary use only. It includes a method for correlating measurement results to allow inter-laboratory comparisons. It is designed to facilitate international cooperation and, possibly, regulation building.
Measurement of tyres using this method enables comparisons to be made between the rolling resistance of new test tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions.d edition 2018-07 Passenger car, truck and bus tyre rolling resistance measurement method — Single point test and correlation of measurement results Méthode de mesure de la résistance au roulement des pneumatiques pour voitures particulières, camions et autobus — Essai à condition de mesure unique et corrélation des résultats de mesure Reference number ISO 28580:2018(E) ？ ISO 2018 ISO 28580:2
