Agricultural flotation tires, particularly 20" rim diameter tires used on fertilizer applicator vehicles, are frequently subjected to significant over-deflection (underinflation and/or overloading). This type of usage can damage the tire in ways that may not be immediately noticed and can lead to a tire failure. This is a particular concern if used on-road at higher speeds (maximum 30 mph).
On-road usage — even for short distances — at speeds higher (maximum 30 mph) than in the field with farm tires that are damaged or over-deflected can cause a sudden tire failure that could lead to serious personal injury or death.
TO PREVENT TIRE FAILURE AND AN ACCIDENT:
- Use the proper tire for the application.
- Always inflate to recommended pressure.
- Do not overload.
- Never exceed the tire speed limit.
Overloading may be resolved by properly fitting another tire, by the addition of a tag or push axle, or by utilizing a nurse vehicle. Application, load, inflation pressure, and maximum speed information can be found in the Firestone Farm Tire Data Book or online at www.firestoneag.com.
