1. Place wheel assembly in inflation safety cage (see paragraph 2-3).
Ensure that tire is totally deflated before removing wheel nuts. Failure to follow proper safety
precautions could cause serous injury or death.
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.
These instructions only provide basic information for the HMMWV bias tire, rim and two-
piece magnesium runflats. Since fielding of the first HMMWV's there have been various
configurations of the HMMWV tire, rim and runflat assemblies (e.g. radial tires, one-piece
rubber runflats etc.). Refer to the latest version of TM 9-2320-280-20 for maintenance
instructions on other HMMWV configurations.
2. Remove valve core (4) from valve stem (3) (see paragraph 2-26) and deflate tire (6). Run a piece of
wire through valve stem to ensure that it is not plugged.
