ABSTRACT A13.6 X 38 tractor tire was operated at the recom-mended load of 16.3 kN and also at half load to simulate dualing. The tire was run four times in the same rut in three different soils. Each soil was freshly tilled and loose before the first pass. Results showed both net traction and tractive efficien-cy significantly lower on the first pass than on subse-quent passes. Sinkage and bulk density changes were noted after each of the four passes. Approximately 75 percent of the total change in bulk density and 90 per-cent of the sinkage occurred on the first pass of the tire.
