|The F-16 and Cougar share a
similar main wheel and tire. The components listed above
are common to both.
filling process is accomplished by air going in through
the fill barb, it passes through the O-Ring One-Way
Valve and into the tire.
There will be a leak that comes
out of the barb if there is any dirt, or a scratch, or
lack of O-Ring lube preventing the O-Ring from seating
against the small hole in the inner rim.
If there is a leak that is not
through the barb, the possibilities are the sealing
O-Ring, or the seal that is made when the two wheel
halves "pinch" the tire against the inner rim, or an
actual hole in the tire itself. These will be easy
enough to identify with a small bowl of water etc...
