| Abstract |
The ability to rank passenger car tires according to their respective rolling resistance facilitates emission and fuel economy testing and can serve as a consumer buying aid. However, at the present time a single, universally accepted tire rolling resistance measurement method is not available. Current practices measure rolling resistance while the tire operated at steady state conditions which are a typical of actual tire use. Emission Control Technology Division is concerned that tires ranked according to typical steady state practices perform differently when operated according to current emissions and fuel economy (transient) tests or in real life. This study was conducted to determine the difference in tire rolling resistance rankings from steady state and transient testing. |
