Coefficients of mechanical behavior of silty-loam soil were accurately measured to obtain an effective simulation. The results of simulation which was implemented in MatLab7, showed that the radial-ply tire had greater tractive efficiency than bias tire at the same conditions on silty-loam soil. Bias-ply tire had greater motion reduction (slip) and gross traction had slightly greater than radial-ply tire when the net traction force was the same for each tire. Also results of simulation and tests showed that the radial-ply tire had less rolling resistance than bias-ply tire on silty-loam soil at the same conditions. Based on simulation results, the effects of slip, inflation pressure and mechanical stiffness of soil on tractive efficiency were satisfactorily predicted.
