This complex phenomenon is a function of many variables, including tire temperature, tire construction, rubber compound, and inflation pressure. While the first element is not easily controllable, the other elements can be controlled by tire selection and pressure adjustment. Road vehicle race teams desire to minimize rolling resistance whenever possible to maximize performance and minimize fuel consumption. This study aimed to characterize the surface- and pressure-dependent rolling resistance of tires for an SAE Baja off road vehicle. In this study, rolling resistance force was experimentally measured via load cell for a range of tire pressures on asphalt. From this, rolling resistance coefficients were extracted for each pressure using a linear model. Tire pressure values corresponding with minimal rolling resistance were tabulated for each tire type and road surface. Armed with this information, the Baja team can adjust tire pressure or consider changing tires according to road surface type in order to optimize performance.Read More
