Pneumatic Tires Adding Liquid Weight Tractor tire can be 80% filled with liquid as follows, 1. Raise the wheel. Rotate the tire until the valve, stem is at 1’O Clock position. 2. Remove the valve core housing and screw on the adapter. 3. Force liquid into the tire from a tank placed at least five feet higher than the tractor tire, or by using a compressor and pressure tank filled with water. 4. When the liquid has reached the required level, remove the adapter, screw in the valve core and inflate to the recommended pressure.

Where ambient temperatures are likely to fall below freezing point use calcium chloride solution, methanol for antifreeze. The instructions and recommendation shown below should be followed in order to secure maximum life and efficient service from pneumatic tires. Inflation Keep tires properly inflated to the pressure as shown in the Chart below. Under inflation will damage tire cord and may cause the tire to slip on the rim and tear out the tube valve stem. Over inflation results in excessive slippage, causing rapid tire wear. Air pressure should be checked once a week with an accurate low pressure gauge having one pound graduations. Air pressure should not be allowed to drop or exceed the recommendations. Always see that the tire valve caps are in place and screwed tight. The caps prevent loss of air through the valve core. Further, they prevent debris from entering and damaging the valve core and air chamber in the tires. Exceptions (Rear Tires only) When plowing with a moulded plow, the left hand or land wheel should be inflated to 2 p.s.i. lesser than right hand or furrow wheel. Chart A-1 Tire Load Rating :
