General Information AGRICULTURAL TIRES SOME POINTS WORTH REMEMBERING Alliance agricultural tires are designed for top performance under all working conditions. They are manufactured for agricultural and forestry jobs, including occasional on the road driving. Before using them for any other type of work consult the manufacturer.  To achieve best results follow these tips:   LOAD AND INFLATION PRESSURE Never overload your tires or drive them either over-inflated or under-inflated. If you know the total weight (load on rig) on the tires, consult the tables on the following pages to determine the correct inflation pressure. If this is not possible, follow the instructions of the tractor manufacturer.  For tractor drive-wheel tires, maintain an inflation pressure of 20 psi (1.4 bar) when employed for industrial use or in full-time on-the-road jobs, even when load is insignificant.  For work in the field it is recommended never to lower inflation pressure below 16 psi (1.1 bar). If, however, a lower pressure is needed for a specific field job, remember to raise it back to the normal required pressure upon completion of that specific task.    RIMS & TUBES Always use the recommended rim size. If, however, the rim used is narrower than the narrowest recommended rim, reduce tire load to the load recommended for the tire one size smaller, maintaining the same inflation pressure.  Always use a new tube with a new tire. Tube size should be identical to tire size. For tractor drive-wheels, use an air-water valve tube.    WATER FILLING  To achieve better traction, fill the tire with water. Done correctly, this practice will not harm the tire or influence its driving properties. In cold climate areas, add anti-freeze substances. The recommended substances are calcium chloride 80% or magnesium chloride 47%.  MOUNTING AND DISMOUNTING Always practice correct mounting and dismounting procedures, and make sure you have taken all safety precautions.  After mounting the tire, inflate it to seat the beads.  Then completely deflate and re-inflate to recommended working pressure.  Remember: Never inflate tractor drive-wheels beyond 35 psi (2.5 bar) when seating the beads.  STORAGE Do not store tires for more than a few months. Storage areas should be dark and cool, free of dirt on oils, as far as possible from running electric engines.
