overload your tires or drive them either over-inflated or
under-inflated. If you know the total weight (load on rig) on the
tires, consult the tables on the following pages to determine the
correct inflation pressure. If this is not possible, follow the
instructions of the tractor manufacturer.
drive-wheel tires, maintain an inflation pressure of 20 psi (1.4 bar)
when employed for industrial use or in full-time on-the-road jobs, even
when load is insignificant.

recommended never to lower inflation pressure below 16 psi (1.1 bar).
If, however, a lower pressure is needed for a specific field job,
remember to raise it back to the normal required pressure upon
completion of that specific task.
use the recommended rim size. If, however, the rim used is
narrower than the narrowest recommended rim, reduce tire load to the
load recommended for the tire one size smaller, maintaining the same

Tube size should be identical to tire size. For tractor drive-wheels,
use an air-water valve tube.
