Abstract: This report analyzes the results of 184 multiple-pass tests with a single, smooth, pneumatic tire (9.00-14r, 2-PR) in a fat clay at a high degree of saturation. These tests were performed using a wide range of tire loads, tire deflections, and soil strengthc. Some of the testc were conducted to study the influence of speed on performance. Basic plots of the data (one dependent versus one independent variable with all other independent variables held constant) show the relative effect of each independent test variable on tire performance. Scatter of the pull and torque data points was found to be quite large for the early tests. An examination of the data showed that a difference in soil strength between the soil surface and the remainder of the soil mass was the probable cause of the scatter. Improvement in soil processing techniques subsequently produced more uniform soil conditions and virtually eliminated this scatter in the later tests. A simple static analysis was found adequate to represent the forces and moments on a towed or powered pneumatic tire operating at small sinkages in a soft clay.
