Preformed Packing (refer to the vehicle parts
Inflator-gage, pneumatic tire (includes 10'
hose) (Item 30, Appendix B)
Tire iron, curved flat type (Item 34,

1. Remove valve core and completely deflate tire (see paragraph 2-26). Run a piece of wire through
valve stem to ensure that it is not plugged.
When dislodging tire beads, lockring, or side ring flanges, be absolutely certain that
no air pressure remains in tire. Serious injury or death could result.
Use tire and rim lubricant as necessary to avoid damaging tire beads or bead seats
during demounting and mounting.
Never use petroleum based products such as oil or grease when demounting/mounting tires
from rims. Petroleum based products have a
severe degrading affect on tire rubber. Use only
approved tire and rim lubricant.
2. Loosen outer tire bead from demountable side ring
flange (1) by inserting a curved bead breaker tire
iron (3) between tire bead and side ring flange.
3. Work progressively around rim (2) rotating curved
bead breaker tire iron (3) down until outer tire
bead is completely free of side ring flange (1).
