The report compares the rolling resistance at 45 PSI as measured on the Clayton Dynamometer from the previous study (Tire-Dynamometer Roll Effects) with recently obtained tire rolling resistance data at 26 PSI as measured on the single large-roll dynamometer and corrected for roll curvature. The report concludes that (1) for vehicles equipped with radial tires inflated to pressures of approximately 30 PSI, two tires at 45 PSI on the Clayton are equivalent to four tires (at 30 PSI) on the road; (2) the Clayton Dynamometer underloads vehicles equipped with bias belted and bias ply tires.
