2Inflation of Tires with Nitrogen (N)
Caterpillar recommends using dry nitrogen (N2) gas for tire inflation and tire pressure adjustments on all rubber tired machines. Nitrogen is an inert gas and will not support combustion inside the tire.
Proper nitrogen inflation equipment, and training in using the equipment, are necessary to avoid overinflation. A tire blowout or rim failure can result from improper or misused equipment.
In addition to reducing the risk of an explosion, using nitrogen instead of air to inflate tires lessens the slow oxidation of the rubber and the accompanying gradual tire deterioration. This is especially important for tires that have an expected long service life (four or more years). It also reduces the corrosion of rim components and the resulting disassembly problems.
Use a self-attaching inflation chuck and stand behind the tread when inflating a tire.
Set the tire inflation equipment regulator at no more than 140 kPa (20 psi) over the recommended tire pressure.
Use only Caterpillar Part 6V4040 Nitrogen Tire Inflation Group, or equivalent, to inflate tires from a nitrogen gas cylinder. Refer to Special Instruction, Form SMHS7867, for tire inflation instructions.Use the same tire pressures for nitrogen inflation that are used for air inflation. (Consult your tire dealer for operating pressure.)Shipping Pressures
The inflation pressures shown in the chart below are cold inflation operating and shipping pressures for tires on Caterpillar machines.The inflation pressure is based on the weight of a ready-to-work machine without attachments, at rated payload, and in average operating conditions. Pressures for each application may need to be varied from those shown and should always be obtained from your tire supplier. The "R" in tire size denotes radial construction.
