For maximum tractor performance, always adjust the tyre
pressure within the minimum/maximum range, to conform
with the actual load on the tyres. Under normal conditions
use the minimum pressure rating for general drawbar
work. Use the higher pressure rating, up to the maximum,
for heavy three point hitch mounted equipment.

EXAMPLE "B"
Example ‘A’ shows the cross section of a tyre inflated
for maximum load but with a minimum load on the tyre.
The tyre tread is not making full contact with the ground
which will give poor performance.

EXAMPLE "A"
Example ‘B’ shows the cross section of a tyre with the
inflated pressure correctly adjusted to the load on the
tyre. The tyre tread is making full contact with the ground
which will give maximum performance.
Tyre pressure can also be adjusted as required to satisfy
the following requirements.
TYRE INFLATION SPECIFICATIONS
A. Severe service. Tyre pressure can be increased 38
kPa, 0.27 bar, (4 psi) more than the maximum pressure
shown in the charts, for tyres used in severe service. Se-
vere service includes the furrow tyre in regular ploughing
operations, and in hillside operations.
B. Tyres with liquid ballast. Inflate the tyres 14 kPa,
0.14 bar, (2 psi) more than the normal operating pressure
required for your operation. This will compensate for aera-
tion that occurs when the tyres are in motion.
WARNING: A tyre can explode during infla-
tion and cause serious injury or death. Never
increase air pressure beyond 241 kPa, 2.4 bar
to seat the bead on the rim. Replace a tyre if
it has a defect. Replace a wheel rim which has
cracks, wear or severe rust. Make sure that all
the air is removed from a tyre before removing
the tyre from the rim. Never use force on an
inflated or partially inflated tyre, make sure
the tyre is correctly seated before inflating.
Make sure the tyre is correctly positioned
before inflating.
See Tyre and Wheel Service on page 169 for instructions
on safe tyre inflation procedure, recommended tyre main-
tenance and tyre/rim repair. See further in this section.
IMPORTANT: During transportation, by rail or road,
tractor tyres are inflated to higher than normal operating
pressures. Before using your tractor check the air pressure
in the tyres to make sure that the air pressures are correct.
