Just a word of warning to those who have or will (that's everybody) replace
a tire on your LNC2 - probably LNC4 as well.

Last fall, I had a main tire go flat on landing. (Our airport is being
worked on, so it appears I ran over some sharp debris - it was a relatively
new tire). Anyway, the tire was changed out on the ramp without the usual
hangar amenities, and several people handled the wheel during the process.

Last Saturday, the same tire went down on landing, this time with only about
10 landings on it. When removed from the airplane and the tire and tube was
off the gear, a close inspection of the wheel - halves revealed a very small
raised burr or nick at the edge of the center parting line. The burr was
about 0.06" long and stuck up no more than about 0.032". It obviously had
occurred during the earlier tire change and wasn't noticed for whatever
reason.

Close inspection of the tube showed that the burr, as small as it was, was
the cause of the flat. The wheel material is easily dinged as it's
relatively soft aluminum, so be warned: check yours carefully when changing
tires - it appears that it takes very little to damage the tubes.

Waiting for new tires and tubes.
