Test results show increased yield with super singles, resulting in $24,000 in annual yield profit potential in a 1,500-acre corn plot.

The Test:
In the spring of 2016, in a cooperative effort with Titan, Missouri farmer and Titan customer Mark Stallings conducted a study to put the Goodyear LSW Super Singles to the test.

Pioneer 2089YHR seed corn was planted in two test plots with comparable historical data. The seed was planted in alternating rows with two identical New Holland T-8 255 hp tractors and 16-row Kinze 3600 planters. The first tractor was fitted with standard 380/80R38 duals on the front and 480/80R50 dual rears. The second tractor was fitted with Goodyear Super Single LSW1000/40R32 fronts and Goodyear Super Single LSW1100/45R46 rears.

Agronomic oversight for the test was provided by agronomists, Jake Mikels and Brandon Dirnberger, from Wheat Tech Agronomy. 

Compaction Results:
Tire depth measurements showed significantly less soil compaction with the Goodyear LSW Super Singles as compared to the standard duals — on average showing a 38 percent reduction in tire depth.

Increased compaction is a result of running standard OEM duals. Additionally, the pressure of the narrow duals causes rutting between the tires.  The pinch row effect from narrow duals showed a negative impact on yields, through stunted root growth development and poor seed germination.

The 20 percent increased footprint of the Goodyear LSW Super Singles significantly reduced ground-bearing pressure.

Yield Results:
The test plot with the Goodyear LSW Super Singles yielded five bushels more per acre compared to the standard duals; on average, 179.01 bushels per acre versus 174.01 bushels per acre, respectively – a $16 per acre advantage, which would equate to $24,000 in annual additional yield profit over 1,500 acres.

These findings reinforce the idea that growers who do not have a need to run their tractors between rows post-emergence can benefit greatly by switching from conventional duals to LSW super singles.

How to make the switch on new equipment

Talk to your Titan or Goodyear^® Farm Tire dealer about exchanging your current conventional dual setup for a super single setup. Many dealers may offer to buy the standard wheel/tire assemblies from you and apply the credit toward a new set of super singles.
