TRUCK TIRE CORNERING AND BRAKING TRACTION STUDY

Twenty-four pairs of truck tires were tested for braking and cornering traction on two wetted pavements at 40 and 55 mph. Locked wheel braking force coefficient, peak braking force coefficient, and peak lateral force coefficient were measured. This sample was used to predict the traction performance of the truck tire population. Comparisons were made between truck tire and automobile tire populations. Correlations between various traction properties of truck tires were computed. Variability between 'identical' tires in traction performance was predicted, and the traction performance of various tire cornering properties in accident avoidance was discussed.
