Within the past 2 weeks we have had 4 flat tires on our 360.
no pinching during assembly of the wheels. All tubes were purchased from Neico
within the last four months.
Does anyone have any ideas why this is happening?
Stu -
I purchased and installed three new tubes on my 320 last summer. No leaks
thus far, so I can't be of any real help for similar experience. I did write
in the LNN last summer of my experience regarding a pinched tube and the use
of silicon lubricant rather than cardboard to eliminate pinching tubes during
wheel assembly. I can only suggest the obvious of blowing up any new tubes
and letting them sit around for a few days to observe for leaking. It may be
that they leak only under pressure, perhaps because the valve stem isn't
seated. Try tightening the valve stems, but not too tight. Other than that,
try fully assembling a wheel and inflating to full pressure and letting that
sit around for awhile...better to happen "on the shelf" than on the plane,
especially when taxiing or landing!
