In order to determine the effects of the twin small-roll dynamometer on tire rolling resistance, EPA has undertaken a program to measure tire rolling resistance on both a twin small-roll dynamometer and a single large-roll dynamometer. The results generated on the single large-roll dynamometer will then be corrected to a flat surface (the road) and a correlation between the twin small-roll dynamometer and the road established with regard to tire rolling resistance. In order to estimate the accuracy of these measurements, three (3) sets of tires (2 tires are a set), each set of different construction type (radial, bias belted, and bias ply), were tested repeatedly under the same conditions (vertical load, cold tire pressure, etc.) on the single large-roll dynamometer. The results of these tests are discussed in this report.
