Several of us have had difficulty checking pressure and adding air to tires with the AirFlex (yellow "composite" tubes with black "nylon" or similar ends). Issue is the center core doesn't extend far enough to press the tire valve with a normal guage or tire air chuck. Several of us have solved by trimming a few threads of the black "nylon" end off, exposing more of the core. The AirFlex extensions are "airless" - only are filled with tire air when the core is depressed and presses the tire valve - e.g. when checking pressure or adding air. If something happens to the extension while driving, the tire should'nt deflate.
As I've mentioned here before, I tie the extensions to the wheel covers and the wheel covers to the wheels to avoid the extensions whipping around while driving. 65 K miles and on second set of tires now with no extension issues.
