Checking Tire Inflation Pressure

Check tires daily for damage or low pressure.

Check inflation pressure with a gauge, at least every 100 working hours. Use a precision gauge with graduated scale at every 10 Kpa (0.1 bar; 1 psi).

If the tires contain liquid ballast, use a special pressure gauge for air/water and measure with valve pin at lower part of tire.

NOTE: When ploughing or working on slopes, tire pressure can be increased 28 KPa (0.28 bar; 4 psi) ABOVE the maximum value to prevent tire deformations.

IMPORTANT: Always check inflation pressure with calibrated pressure gauge to avoid excesses. Excessive pressure reduces performance and increases force applied to tire and rim.

NOTE: The following information on inflation applies to both front and rear tires.

1. All inflation pressures are calculated for a maximum forward speed of 29 Km/h (18.0 mph).
2. Operating the tires at the indicated pressures contributes to optimum tire performance.
3. Inflation pressures less than 80 Kpa (0.8 bar; 12 psi) should be regularly controlled due to greater risk of air leakage.
4. For tractors working on slopes, hills pressure should be increased to 28 Kpa (0.28 bar; 4 psi) above the values indicated to compensate for lateral weight transference.
5. Narrow tires in high traction conditions can sometimes separate from their rims if they are not seated properly, or even if a lot of lubricant was used in mounting. Increasing inflation pressure will compensate for this condition without reducing traction.
6. If more load capacity is needed, consult your John Deere dealer to obtain load and inflation chart information from the tire manufacturer.
