It is not uncommon in off-road mobility for vehicles to operate over varying types of terrain. In situations where inorganic clay soils constitute the primary substrate material, considerable differences in soil stability and compliance characteristics can occur because of local variations in soil type, density and water content. This study takes into account the above constraints in the methodology developed for evaluation and prediction of efficient tyre performance. This requirement for capability in development of efficient tyre traction on soil for mobility purposes is critical if off-road operations are performed in remote regions where minimum fuel expenditure is particularly important. The developed analytical procedure utilizes the experience gained from experimental tow-bin tests which studied tyre-soil interaction under varying tyre and soil conditions.
