“A Commented Synopsis of the Report of the Committee for the National Tire Efficiency Study”

Marion G. Pottinger1, Joseph D. Walter2, and John D. Eagleburger3

The Congress of the United States petitioned the Transportation Research Board of the National Academy of Sciences to study replacement passenger tire rolling resistance in 2005 with funding from the National Highway Traffic Safety Administration.  The study was initiated to assess the potential for reduction in replacement tire rolling resistance to yield fuel savings.  The time required to realize these savings is less than the time required for automotive and light truck fleet replacement. 

Congress recognized that other factors besides fuel savings had to be considered if the committee’s advice was to be a reasonable guide for public policy. Therefore, the study simultaneously considered the effect of potential rolling resistance reductions in replacement tires on fuel consumption, wear life, scrap tire generation, traffic safety, and consumer spending for tires and fuel.  This paper summarizes the committee’s report issued in 2006.
The authors, who were members of the multidisciplinary committee, also, provide comments regarding technical difficulties encountered in the committee’s work and ideas for alleviating these difficulties in further studies of this kind.  The authors’ comments are clearly differentiated so that these comments will not be confused with findings, conclusions, and recommendations developed by the committee and contained in its final report.
