In succession to part 1, dynamic tests were conducted in part 2 to determine the characteristics of a nonrolling 8.3R/24 radial agricultural drive tire. The dynamic stiffness and damping properties in longitudinal and lateral directions were experimentally derived from the vibratory motions of a cable-suspended plate pressed against the tire periphery. The results indicated that the variations of the dynamic spring constant of the tire exhibited trends similar to those obtained from the static tests but were 4%-20% and 1%-18% higher in the longitudinal and lateral directions, respectively. In addition, dynamic damping coefficients were significantly higher than static ones.
