Abstract
Experimental or observed rolling resistance data can be utilized to develop an empirical model that accurately depicts tire rolling resistance as a function of load and pressure over a wide range of load and pressure variations. This method allows the development of a graphical expression (carpet plot) or mathematical expression (computer modelled) to depict rolling resistance on three "control tires." When the graphical or computer modelled systems are combined with a basic control tire correlation concept, a rather accurate inter-test facility prediction system does not have a rely on the sometimes inaccurate correction equations developed from theoretical modelling techniques.
