FACTORS AFFECTING THE SKIDDING PERFORMANCE OF TRUCKS

A comparison is made between the skidding performance of trucks and cars with respect to the estimation of vehicle speeds from skid marks. Load distribution, weight transfer, and the number of locked axles are shown to be important factors in the accurate estimation of truck speeds. Evidence is presented which indicates that truck tires have inherently worse skidding performance than car tires on dry pavement and on icy surfaces. The differences are attributed to tread rubber compounding effects and high unit loading in the footprint of truck tires.
