Abstract |
The paper analyzes the tire rolling resistance data obtained in a recent EPA road load project. Variations in the observed tire rolling resistances were analyzed versus tire type, tire manufacturer, and tire size. The fuel economy effect of a change in tire types; that is, from bias to radial tires, has been previously reported and is briefly discussed. From these results it is concluded that a 10 percent change in rolling resistance will yield approximately a 2 percent change in the vehicle fuel economy. At the present time, reduction of fuel consumption through optimization of tires cannot be expected to occur since there is no uniform method of rating and reporting tire energy dissipation. The development of a consistent, uniform method of rating and reporting tire energy dissipation over cyclic driving schedules, such as the EPA test schedule, is recommended. |
