F a r m T i r e s 66 M T D D e c e m b e r 2 0 1 8 use IF, VF and flotation tires to minimize the compaction caused by their tractors, combines, grain carts and manure tanks but then go back out on the field with an air seeder that weighs 20,000 or more pounds, running on highly inflated tires, and cause the exact problem they had been trying to avoid. With the introduction of Alliance VF implement tires over the past year or so, farmers can go all season on low inflation pressure and minimize their compaction from spring fieldwork through harvest. Apollo Vredestein: Both IF and VF are increasing in popularity for very large tractors. Typical applications are 4WD (four-wheel drive) tractors (8 equal size tires) and large MFWD (mechanical front wheel drive) tractors, many coming here from Europe. Implements such as grain carts and heavy tillage tools are also starting to use them. BKT: e demand for IF/VF tires seems to continue gaining steam. More are being used as original equipment on implements and sprayers. Most heavy self-propelled sprayers are coming with IF or VF tires to carry the heavy weight and 40 mph speeds that they run. More IF and VF tires are being used on implements as they get bigger and heavier. e sizes are taller and wider. e demand for these tires will only increase as equipment changes. Bridgestone: IF/VF tires are more oen used in applications that require heavy axle loads, like high-clearance sprayers, combines, grain carts, and transport tires on large implements. As customers require more and more productivity from the equipment they purchase, equipment manufacturers are meeting the need for more capacity. When equipment gets big- ger or has more capacity, the axle weights increase. Heavier loads require either larger tires or an increase in inflation pressure to carry the load. A high-clearance sprayer with 120-foot booms and 1,200 gallons of liquid requires each tire to carry 12,000 to 14,000 pounds. Class 8 and 9 combines' front axle weight can exceed 65,000 pounds with a 40-foot draper platform or 16-row corn head with 400 bushels of crop in the bin. Implements that are 50- to 60-feet wide in the field have to fold narrower for road transport, which transfers the implement's weight to the four tires. ese applica- tions are using IF or VF tires to carry the increased weights while minimizing the need for more inflation pressure. CEAT: is technology fits the self-pro- pelled row crop sprayer market extremely well with the development of GMO row crops. Due to the additional trips across the fields with herbicide applications, the row crop sprayers have increased in size to improve efficiency and help get the applications completed on a more timely basis. ese sprayers are running the same tracks with each application so it became much more important to carry these large loads and to minimize compaction. Implement tires are a more recent development for the IF and VF tires. e largest planters along with other heavy implements have always had trouble carry- ing these big loads. Larger equipment has led to adding additional tires to manage these loads. Incorporating the IF and VF tires on these large, heavy implements can provide the load carrying capacity and reduce the compaction compared to the standard bias or radial implement tires. Planting windows seem to be tighter than ever and reducing down time has become more critical. Adopting the IF and VF tires for these large planters does reduce potential down time and of course allows the planting operations to proceed under less than ideal conditions. GRI: IF/VF started with row crop, sprayer and flotation R1 and is expanding in all sizes including radial implements. Manufacturers are now adding more sizes as IF/VF advantages increase ser- vice life and reduce overweight failures/adjustments. Michelin: Demand is increas- ing for more applications, fitments and implements. Today's latest tire technologies enable farmers to carry a heavier load at the same air pressure compared to standard radial technology, or the same load at a lower pressure. In addition, a larger tire footprint allows for better traction in the field, less slippage and improved fuel economy. Michelin offers a portfolio of IF and VF tires for tractors, sprayers and harvest machines in a selection of sizes. Trelleborg: All tire manufacturers are continuously introducing more sizes under IF and VF technology. As new equipment is launched in the market and their power and weight increase, they require larger tires and/or tires that can hold more load. e fastest segment adopting the IF/VF technology is the sprayers, followed by large tractors. ADVANCEMENTS IN TECHNOLOGY MTD also asked manufacturers for an update on their latest IF and VF technologies. Alliance: IF and VF tires are very demanding to design and manufacture; they require state-of-the-art compounds, and everything from the bead to the tread has to be built to exacting standards. At Alliance, we've combined the expertise we've developed in IF and VF tires with our decades of leadership in flotation tire technology to help pioneer the VF flotation tire category. To complement our IF and VF R-1 and R-1W tires, we introduced the Alliance Bridgestone says its Destination Turf radial implement tire combines its IF and VF technologies with a new turf tread design that deflects stubble and absorbs more damage. The contact patch of the second- generation CerexBib 2 from Michelin expands up to 35%, which helps reduce soil compaction and protect the soil for future harvests.
