Abstract A recent EPA Technical Report (1) presents the results of a program which relates tire rolling resistance measurements conducted on a Clayton twin small-roll dynamometer to those on a LABECO single large roll (48 in. diameter) dynamometer. The report extrapolates the results obtained on the LABECO to the road by the application of a curvature correction factor developed as a result of tire testing on both a flat surface machine and a large (67 in. diameter) roll dynamometer. This factor has been reported in the technical literature (2). In the EPA study, all tests were conducted at 45 PSIG cold inflation pressure which is the typical tire pressure used for emissions and fuel economy testing on the dynamometer. In order to determine the effect of tire pressure on rolling resistance, data were collected on the same tires used in the above study at a cold inflation pressure of 26 PSIG. These data were then combined with the 45 PSIG data for statistical comparison.
