6. All Tires.
Always use an inflation safety cap to inflate tire/rim assembly not mounted on a tire
changing machine that has a positive lock down device designed to hold the assembly
during inflation. When using a tire changing machine, always follow the manufacturers
mounting and safety instructions. Failure to do so could cause serious injury or death.
When inflating tires in an inflation safety cage, always use an extension airhose and a
pneumatic tire inflator-gage. Failure to do so could cause serious injury.
Never lean, stand, or reach over tire/rim assembly during inflation. Serious injury or death
Never put hands or fingers near rim flanges or bead seats when inflating tire. Serious
injury could result.
Never inflate tires over 40 psi (276 kPa) to seat tire beads. If beads do not seat, deflate,
demount, and check the tire/rim match. Mount and lubricate according to instructions.
Serious injury or death could result if these procedures are not followed.
(a) If a tire changing machine with a positive lock down device is not available, position tire in an
inflation safety cage. Using an extension airhose and a pneumatic tire inflator-gage, inflate tire to 40
psi (276 kPa) to seat tire beads. If tire beads do not seat, deflate and demount tire, correct the
problem, mount tire using additional tire and rim lubricant on both beads, then repeat this step.
(b) When both tire beads are properly seated, allow tire to deflate, then install valve core (see paragraph
2-26). Inflate tire to normal operating pressure.
(c) Check tire pressure, then install valve cap finger-tight.
(d) Remove tire/rim assembly from inflation safety cage, as required.
(e) Balance tire according to balancing machine instructions.
