John Deere offers a variety of tire, wheel, and track options to match soil, terrain and front-end equipment requirements. When selecting the tire that best matches the harvesting application consider the tire size, load index and inflation pressure ride characteristics desired. Reference the charts below tire designation definitions.

 

 
The Tire and Rim Association (TRA), the standardizing body for the tire, rim, valve and allied parts industry in the United States, called for the terms IF/VF/CFO being standard across all brands. The chart below describes the definitions and characteristics of these terms.
 

  IF
Increased flexion
VF
Very high flexion
CFO
Cyclical field operation
LSW®
low sidewall 
Description Carries 20 percent higher loads at same inflation pressure as standard tires or same loads at 20 percent lower inflation pressure as standard tires. Carries 40 percent higher loads at same inflation pressure as standard tires or same loads at 40 percent lower inflation pressure as standard tires. Handles 55 percent higher loads when traveling less than 10 mph, for use on combines and grain carts. Larger rim diameter than standard tires, meets TRA standards for VF/CFO in terms of load/inflation capabilities.
Benefit Reduces soil compaction when properly inflated. Reduces soil compaction when properly inflated. Reduces soil compaction and reduces need to adjust inflation during significant changes in weight during harvest. Reduces soil compaction when properly inflated, minimizes road lope and power hop regardless of inflation pressures.
Caveats Only effective if pressure is adequately maintained by application and weight, increased flex can cause problems with road lope and power hop quality if inflation is not maintained. Only effective if pressure is adequately maintained by application and weight, increased flex can cause problems with road lope and power hop quality if inflation is not maintained. Compaction reduction gains are only realized if proper inflation pressures are maintained. Requires appropriate size of wheel.
