Tractive performance tests were performed with four 1-3 traction implement tires on concrete. Differences in the tires were lug angle, lug pattern and tire profile. Net traction, towed force, load transfer, actual velocity and axle speed were measured. Pull-to- dynamic load ratio, tractive efficiency 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 four tires.
