Normal Stresses at the Tire-Soil Interface in Yielding Soils

Small diaphragm-type pressure-sensitive cells were set flush with the outer surface of a smooth pneumatic tire. Tests were run to determine the magnitude and distribution of normal pressures at the tire-soil interface of a driven and towed tire at several loads and inflation pressures. Tests were conducted on both cohesive and noncohesive soils. The test soils were carefully prepared to a consistency that would allow the soil to yield under the applied load. In the tests reported, the different combinations of test variables produced ruts that ranged from a fraction of an inch to several inches in depth. It was found that the pressure-distribution patterns that occur in the two soil types are different. Typical patterns are shown and some general relations between the patterns observed and the test variables are presented.
