Improperly inflated tires can cause excessive heat build-up, resulting in blowouts.Proper inflation equipment and training in its use are necessary to avoid overinflation. A tire blowout or rim failure can result in accidents or personal injury.Use a self-attaching 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.
Over or under inflated tires can cause excessive or uneven tire wear or rim damage.Keep the valve caps on to prevent dirt from entering the valve stems. Otherwise, valve damage can occur.
100 kilopascal (kPa) is equal to 1 bar (kg/cm2).Have your tire dealer inspect tires with deep cuts or gouges.Measure the tire pressure if a tire appears improperly inflated.Check the inflation pressure with the tires cold and at the same outside temperature in which the machine will operate. Use a Caterpillar 4S6524 or 1P0545 Tire Pressure Gauge or equivalent.When inflating tires in alheated area, make allowances in pressure for cold, outside temperatures. Refer to Special Instruction SMHS7867 for tire inflation instructions.Operating Tire Pressures
For normal operating conditions, inflate the tires to 110 kPa (16 psi). If more floation is required, use a minimum of 82 kPa (12 psi).Transporting Tire Pressures
When transporting the machine, inflate the tires to 206 kPa (30 psi).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. 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 only Caterpillar Part 6V4040 Nitrogen Tire Inflation Group 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.
