A flotation tire’s larger footprint can drive yields higher, help your sprayer conquer wet conditions, and save you money by boosting fuel economy.
How much larger is the footprint of a sprayer flotation tire? A standard IF380/90R46 Firestone with a load index and speed rating of 168D has a flat plate area (footprint) of 273 square inches.
A non-IF 650/65R38 (the most common flotation tire size) Firestone Radial 9000 with a load index and speed rating of 166D has a flat plate area of 390 square inches. That’s an additional 117 square inches of ground contact per tire. And that larger footprint means:
Compaction, which will restrict root development, can thin your stands and lower your yields. When crossing your fields for a pre-plant, pre-emergence, or post-emergence application, you want to limit compaction as much as possible. A flotation tire’s larger footprint will help you minimize compaction’s impact on your bottom line.
Soft and wet spring soils can wreak havoc on your planting plans. Flotation tires will help power you through those pesky wet spots. And they also make it easier to drive straight—and stay on the row after your crop is up. You’ll be surprised at the difference larger sprayer tires make!
Sinking tires also mean sinking fuel economy. You need every aspect of your farm to operate at peak efficiency, so you can’t afford to have the wrong sprayer tires on your equipment.

Load index and speed rating depend on the size of the machine and tire. That said, the most common load index and speed rating that we recommend for self-propelled sprayers is 166D.
We have installed tires with a load index and speed rating of 157A8 (rated for 9,100 lbs at 25 mph), but these barely meet the requirements for some sprayers and won't work on larger sprayers.
For the most common sprayers (Case IH Patriot 4000 series and John Deere 4038 and 4830 series sprayers), we recommend a load index of 160 or greater and a speed rating of B or better (D or E).
