3-14. WHEELS AND TIRES (Contd)
f. Tire Inflation.
(1) General.
Tires require a weekly pressure check. Inflation pressure is one of
the most important elements of tire care. Pressure recommendations for all tires
on all models have been carefully selected to provide good tire life (refer to
table 1-7 for recommended tire pressures). Check and adjust tire pressures when
tires are cold, because pressures normally increase during operation. Never
decrease pressure of warm tires except for operations in mud, sand, or snow.
Reinflate tires which were deflated for operations in cross-country, mud, sand, or
snow. After operations are completed, tires must be removed, and reinflated in a
tire inflation cage by maintenance personnel.
(2) Tire Gaging.
WARNING
Stand clear of tire while gaging and inflating. Injury or death
to personnel may result from exploding wheel components.
(a)
Remove tire inflation gage (10) and hose (4) assembly from stowage
compartment.
(b)
Start at one corner of vehicle and gage all tires. Remove tire valve caps,
apply tire gage air chuck (8) on tire valve stem (7) and press down to read tire
pressure on gage dial (9). Reinstall tire valve caps and tighten caps finger tight.
(3) Tire Inflation.
(a)
Start engine (refer to para.
2-14 or 2-15) anti apply parking brake.
Make sure air reservoir pressure is higher
than recommended tire pressure by
checking air pressure gage on instrument
panel.
(b)
Remove coupling half cover (3).
Install hose coupling half (5) to left-front
emergency air coupling half (1) to inflate
front tires, and right-rear emergency air
coupling half (1) to inflate rear tires.
Turn air valve handle (2) 90 degrees
counterclockwise to release compressed
air to gage (10) and hose (4) assembly.
(c)
Remove tire valve cap, apply air
chuck (8) on tire valve stem (7), and
press down firmly. Depress air chuck
lever (6) to inflate tire. Release lever (6)
momentarily to read tire pressure on
gage dial (9). Adjust tire pressure as
necessary.
