From Two Rivers Marketing:
Tire Manager (by Titan and Goodyear Farm Tires) allows growers and tire technicians the ability to calculate optimum tire inflation pressure for agricultural equipment by simply entering tire size, application, axle weight and specifying singles or duals. The calculator works for any brand of metric, agricultural radial tire. The app features a quick-search tire finder function and allows users to save commonly accessed tires to their list of favorites. Favorite tires can then be accessed without an Internet connection, and inflation pressures can be easily recalculated whenever adjustments to application or axle weight are made. Tire Manager eliminates the need to carry around extensive load/inflation table data, and helps growers ensure their tires are properly inflated for optimum performance and durability.
