Centerline wheel Pro Drag - Air leaking out of wheel - DAGNABBIT!!!!!!!!!

Two pair of 15x3 1/2 centerlines, no tubes. But I don't run drag fronts, just street tires.
Got a pair of cragar supertrick fronts too. Those HAVE to have tubes, and I don't use em on the street.
Three pair of big rear centerlines, two pair of moderate sized rears. One large pair needs tubes, but that is all on the tires, they bleed air like a colander.
