Radial tractor tires offer advantages over bias-ply tires that usually result in increased productivity and reduced fuel consumption.

The axle power developed by a tractor is distributed four ways: overcoming rolling resistance, wheel slip losses, tire-soil action and useful drawbar work. The most efficient use of tractor power occurs when the drawbar power is maximized and the first three items are minimized.

Radial tractor tires can improve tractive efficiency and extend tire wear. There are benefits and disadvantages of radial tractor tires compared to bias-ply tires. Radial tractor tires should be considered as original equipment on new tractors and as replacements whenever tractor tires are being replaced.
