The Alliance 331 Flotation diagonal forestry tire is developed mainly for use on modern forestry Harvesters and Forwarders. In addition, the tire is highly applicable for wheeled excavators, loaders and dumpers, working under heavy terrain conditions. The application in agriculture, especially on heavy and abrasive surfaces, is also suggested. The tire is designed for high traction abilities, low slip and low fuel consumption. Besides that, huge tire volume contributes to low soil compaction and ride comfort in forestry and agricultural applications. The main construction characteristics of the tire are strong nylon casing and steel belts, high undertread gauge, strong and thick sidewalls, special tread compound and protective mud guard. All of this promise long tire life under heavy working conditions in the forests, as well as, smooth and long lasting work in agriculture.
