Titan International shares LSW planting test results

Titan calculates that a farmer could pay off an LSW upgrade in less than a year

Titan International’s Low SideWall, or LSW tyres have been sold to the UK construction sector for the past year, however they are also gaining acceptance amongst agricultural users over in the USA and are prized by many for their reduced soil compaction characteristics, as well as the reduction in road lope and power hop they bring. The Titan LSW agricultural tyres are sold under the Goodyear brand name.

One farmer (and New Holland dealer) from the US state of Missouri wished to verify whether his Goodyear LSW Super Single tyres were indeed improving his bottom line, so last spring he put them to the test in a corn and soybean plot. The harvest data is rolling in, and recently Titan International chairman and chief executive Morry Taylor and Paul Reitz, the company’s president, met with the farmer, Mark Stallings, to review the findings.

Stallings tested Goodyear LSW Super Single tyres in a head-to-head test with Michelin standard dual tyres. He chose two fields with comparable historical data and planted Pioneer 2089YHR seed corn and Bayer Credenz 4878 soybeans. Agronomic oversight for the test was provided by agronomists Jake Mikels and Brandon Dirnberger from Wheat Tech Agronomy. Last spring, the test plots were 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 Michelin duals 380/80R38 on the front set at 20 psi and 480/80R50 rears set at 15 psi. The second tractor was fitted with Goodyear LSW1000/40R32 fronts at 12 psi and Goodyear LSW1100/45R46 rears at 8 psi.

The tyre depth measurements taken during the corn planting are shown in the accompanying Table 1, with an average of 1.580 with Goodyear LSW Super Singles versus 2.550 with Michelin Duals.

Increased compaction, notes Titan, is a result of running standard OEM duals. Additionally, the pressure of the narrow duals causes rutting between the tyres. That pinch row effect from narrow duals showed a negative impact on yields, through stunted root growth development and poor seed germination. The accompanying graphic (Singles vs Duals) shows the centre line of corn rows in reference to the tyre track for both tractors. The 20 per cent increased footprint of the Goodyear LSW Super Singles reduced ground-bearing pressure. As can be seen in the photo of the corn stalk comparison from the growing season, the LSW-equipped tractor produced taller and healthier corn.

In September, results from the corn harvest showed that the test plot with the Goodyear LSW Super Singles yielded 5 bushels more per acre compared to the Michelin duals; on average, 179.01 bushels per acre versus 174.01 bushels per acre, respectively. That represents a US$16 per acre advantage to Mr. Stallings’ bottom line, without taking into consideration a claimed five per cent savings on fuel cost. The results of the soybean harvest showed that the Goodyear LSW Super Singles yielded 6 bushels more per acre compared to the Michelin duals; on average, 83 bushels per acre versus 77 bushels per acre, respectively. That yield increase translates to almost $60 per acre advantage. With those corn yield increases alone and the set up that Stallings uses, Titan calculates that a farmer could pay off an LSW upgrade in less than a year.

Titan has another test site in northwest Illinois that it expects to back up the findings from the southeast Missouri trial. Taylor commented: Titan’s entire LSW team is very excited about this news as it’s been a priority to get real data on how good these tyres are for farmers and confirming Titan’s statement that these tires make every piece of equipment perform better. I’m very happy for all of the Titan team and look forward to working with farmers and dealers to increase their yields. The OEMs will realise the benefits of the Goodyear Farm LSW technology and will be shocked that they could have had these LSW tyres on their equipment five years ago.” Stallings also commented that area farmers are coming to see the LSW Super Singles and asking him about the yield increase.

This winter, Taylor will attend various FFA (Future Farmers of America) meetings and talk about the Goodyear LSW Super Singles. “I’ll enjoy talking to them,” he commented. “We support numerous FFA organisations across the country. These kids are the future of ag in America and they need to be aware of the innovations available to their farms.”

Titan is also testing benefits of Titan LSW tyres on construction and mining equipment and will share results once available.
