Testing of Truck Tire Traction for Load and Aging Effects

A study was conducted for the purpose of evaluating the effects of load and age on truck tire traction performance. A statistically designed experiment was utilized for this purpose. The general methodology of traction data analysis and presentation is given. A method of presenting traction data via a matrix, utilizing the concept of Least Significant Difference is shown. This method provides a basis for better decision making.

The results of the study indicate that load can have significant impact on truck tire traction. All aspects of dry traction are affected by load as is wet peak traction. Load was observed to have no significant effect on wet slide traction. Tire aging was found to have no significant effect on any aspect of truck tire traction.
