Performance of I-3 Traction Implement Tires on Sod and Soil 871608

Tractive performance tests were performed with five I-3 traction implement tires on bermuda grass sod and McLain silt loam soil. Differences in the tires were lug angle, lug pattern and tire profile. Each tire was operated with three static loads and three inflation pressures. Net traction, towed force, load transfer, actual velocity and axle speed were measured. Pull-to-dynamic load ratio and wheel slip were calculated. Curves were fit to the data to describe tractive performance. Significant differences were found in the pull-to-dynamic load ratio of the five tires.
