M o d e r n T i r e D e a l e r . c o m www.vipal-usa.com Facebook: Vipal Rubber Corp SCOTT SLOAN , ag product manager/ global LSW, Titan International Inc.: I do believe we will begin to see more and more onboard inflation systems showing up in the U.S. in the next five years. As precision farming presses on from the sci- ence of the seed, application and condition standpoint, growers are going to be looking for other opportunities to improve machine performance. As tire technology has evolved with deflection technologies like IF and VF, it has enabled growers to run at lower inflations up to 40% lower. However, inflation pressure for trans- port may be different than inflation in the field. Growers will not get out of their machine to drop inflation pressures for 20 minutes to operate in the field, then re-inflate for another 30 when they get back on the road. Knowing this, we as the tire industry educate them to inflate the tire for the worst case scenario. is eliminates the possibility of damaging the tire due to an overloaded and underinflated condition. By doing this the grower is giving up footprint area in lighter conditions such as planting, which may hinder the yield. e idea of the onboard inflation system is that it allows the grower to easily and relatively quickly adjust the inflation pres- sures in the tires from the comforts of the cab. is then allows them to maximize the tire's footprint based on the load for each individual task, hence reducing compaction and potentially increasing yields. Cost, however, is still a hindrance for the technology. Aermarket systems are approximately $15,000, and at $3 corn the decision to pull the trigger on the system relies greatly on that customer's idea of the chances of them recouping their cost in additional revenue. BRADLEY HARRIS , manager of global agricultural field engineering, Firestone Ag Division, Bridgestone Americas Tire Operations LLC: Yes, central tire inflation pressure systems (CTIS) will become more popular on agricultural equipment in the future. When properly used, these systems can lead to improved traction in the field and reduced soil compaction, which can improve crop yields. ese systems allow farmers to quickly manage the inflation pressure in the tires when the axle weights on equipment changes between field and the road. This is why CTIS systems are becoming popular in Europe. A CTIS system makes sense for tractors when the axle weight changes between road transportation and field operation. The most common scenario in North America would be the planter tractor with a 2-point mounted, front fold planter. During road transport, the planter wings fold forward and the planter weight is carried on the rear axle of the tractor and only four tires on the planter. Weighing a 235 horsepower MFWD tractor with a 16/32-inch row front fold planter, the rear axle weight of the tractor is around 27,000 pounds during road transport. When the planter is unfolded in the field, the weight of the planter is now taken off the rear of the tractor and is being carried primarily by the eight tires on the planter. Now the rear axle weight of the tractor is 16,500 pounds. With dual 480/80R50
