The Effect of Tire Lug Height on Off-road Locomotion

Abstract

To improve the trafficability of terrain vehicle, the lug has been attached to the tire. In recent years, the high lug tire is standardized as the normal equipment for agricultural tractor. In this paper the effect of the height of lug was investigated using four wheels with the same diameter, but different height of lugs. The small scale soil bin was used for the experiment. The high lug tire showed a good contribution to improve the trafficability on clayey soil, but not on sand.
