CHAPTER 2. CARE, MAINTENANCE, AND INSPECTION (Con't)
SECTION I. GENERAL INFORMATION (Con't)
2-3. INFLATION SAFETY (Con't).
a. Inflation Safety Cages and Restraining Devices (Con't).
(5) Tire inflation will be controlled from a minimum of 10 ft (3.05 m) away using an extension
airhose, a in-line pneumatic tire inflator-gage and snap-on air chuck. For specific tire inflation procedures,
refer to the applicable procedures for the type of tire being inflated and to the appropriate vehicle TM .
b. Inflation Safety, Multi-Piece Rims with Demountable Lockrings or Side Flanges.
(1) A safety inflation cage must be used for inflating all tires that are mounted on multi-piece
rims with demountable lockrings or side flanges. When a tire is being partially inflated to seat the bead,
without using a safety inflation cage, inflate only to a pressure great enough to seat the flange and tire
bead onto the rim ledge (this is approximately 3 psi).
(2) Remove the valve core to completely deflate tires before demounting them.
(3) Remove the valve core to completely deflate the tire before taking the rim/wheel off the axle
when inflation pressure is 80% or less of the recommended tire pressure, or when there is damage to the
tire or rim/wheel components. Tires with over 80% of the recommended pressure may be inflated on a
vehicle if a clip-on air chuck is used.
(4) Never inflate tires on the floor or within any other solid surface that is within three feet of the
(5) All persons must stay out of the trajectory when tires are being inflated.
(6) Tires must not be inflated to more than the inflation pressure molded on the tire sidewall or
the maximum pressure of the rim/wheel unless a higher pressure is recommended by the manufacturer or
indicated in the vehicle Technical Manual.
(7) After tire inflation, the tire and rim/wheel components must carefully be inspected while still
in the safety inflation cage to ensure they are properly seated and locked. If adjustments are required, the
tire must be completely deflated by removing its valve core while the tire is still in the safety inflation
cage before adjustments are made.
(8) Never attempt to correct the seating of side flanges or lock rings by hammering or forcing the
components while the tire is inflated.
(9) Even after inflation and inspection for properly seated components, stand clear whenever
handling multi-piece rims/wheels. With the exception needed to mounting the assembly on the vehicle, try
to remain out of the wheel and air blast trajectory as much as possible until the assembly has been
mounted on the vehicle and operated.
