MECHANICAL PROPERTIES OF AN OFF-THE-ROAD TIRE

Four 20.5-25/16 off-the-road tires have been tested in order to obtain their static and dynamic properties. Quasi-static tests were performed to obtain static spring rates and loss energies. Drop tests were conducted with various weights and tire inflation pressures to obtain dynamic spring rates and damping coefficients. Dynamometer tests were performed at various loads, speeds, and inflation pressures in order to determine temperature buildup. Yawed roll tests are reported that provide carpet plots of cornering force and aligning torque versus slip angle and normal load. /Author/
