Slippage was significantly reduced on all surfaces. Due to radial tire construction, tires have less tendency to have tire lug-induced vibrations. Increased drawbar pull. Depending on the surface conditions, the pull may be increased 6 to 10 percent without the addition of ballast. Extended tire life.
Radial tires are heavier than bias-ply tires of equal size, partly because of higher lugs.
Tire life is extended by as much as 30 percent over bias-ply tires doing comparable work. Poor transport handling characteristics. Tire sway increases as speed increases. This is probably due to low lateral carcass stiffness that produces poor handling during transport speeds. Lower transport speeds may be necessary for safe road travel.
