Check Tire Inflation Pressure

SERVICE INTERVAL
	Weekly or 50 Hour

Consider the Following When Inflating Tires:

• At least every 50 hours of operation, check inflation pressure with a gauge. Use an accurate gauge having 10 kPa (0.1 bar) (1 psi) graduations. If tires contain liquid ballast, use a special air-water gauge and measure with the valve stem at bottom.
• Correctly inflated radial tires show a large deflection of the sidewall or “cheeks.” Deflection is normal and does not hurt the tire if the inflation pressure is maintained.
• Over-inflation reduces performance and increases strain of both tire and rim.
• Regularly monitor inflation pressures less than 80 kPa (0.8 bar) (12 psi) because of the increased risk of low pressure leaks (especially due to leaking valve cores).
• When operating machines on steep side slopes, or furrow plowing increase inflation pressures 28 kPa (0.28 bar) (4 psi) above the values listed to compensate for lateral weight transfer.
• Tires run as singles in high traction conditions sometimes experience bead slip. Increasing the inflation pressure compensates for this condition but causes reduced traction.
• If higher load capacities are needed, contact your John Deere dealer for tire manufacturers load and inflation table information.
• Maximum tire pressure is specified on the tire sidewall.
• Increase front tire pressures 30 kPa (0.3 bar) (4 psi) above values listed when operating with a loader to compensate for weight transfer.
