Remember folks, the tire valve core has a basic opening pressure. your compressor must at least have that pressure over the desired pressure to get the air into the tire.
want to prove that? use an old rubber tire filler with a core in it, connect it to your compressor, set the regulator at 0 and slowly add pressure until the valve core opens.
Ive seen them as low as 10 psi, and as high as 80 psi.
Valve core is pushed open by the metal peg in the center of the chuck that also opens the chuck. Want to prove it? take a chuck, not connected to an air hose and push it on the core, air comes out because the chuck opens the core.

mine screws on and works on a pressure differential.
