Check tires daily for damage or noticeably low pressure.
At least every 100 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 valve stem at bottom.
NOTE:
When furrow plowing or during hillside operation, tire pressure can be increased 28 kPa (0.28 bar) (4 psi) ABOVE maximum to prevent tire wrinkling or buckling.
NOTE:
Following inflation information applies to both front and rear tires and Tire Inflation Pressure Chart.
1.
All inflation pressures are calculated for 29 km/h (18 mph) travel speeds.
2.
Check tire inflation pressure while tires are cool, using an accurate dial or stick-type gauge having 10 kPa (0.1 bar) (1 psi) graduations. Over-inflation reduces performance and increases strain on both tire and rim.

3.
Operation of tires at the inflation pressures listed on chart will result in optimum tractive performance of the tire/vehicle system.
4.
Inflation pressures less than 80 kPa (12 psi) should be monitored regularly because of the increased risk of low pressure air leaks (especially due to leaking valve cores.)
5.
Tractors operating on steep side slopes should increase inflation pressures 28 kPa (4 psi) above the values listed to compensate for lateral weight transfer.
6.
Tires run as singles in high traction conditions sometimes experience bead slip if the bead was not fully seated or if too much lubricant was used to mount the tire. Increasing the inflation pressure will compensate for this condition but will not cause reduced traction. Consult your tire dealer if this problem occurs.
7.
If higher load capacities are needed, contact your John Deere dealer for tire manufacturer's load and inflation table information.
