Slip Rate

To improve tractor performance, calibration pressures should be properly adjusted to allow for maximum traction and minimum soil compaction.

Pressure on the ground (soil compaction) should be from 0,20 to 0,27 bar (3 to 4 psi) above tire calibration pressure (in case of bias tires).

Consult Tire Calibration Pressure Chart to determine appropriate calibration pressure.

Make sure that tire load capacity is not exceeded when ballast is added. Also check liquid ballasting weight table, see Using Liquid Ballast in Tires.
