No idea how it got flat. It was a small hole in the tube, and it looked and > rolled fine before takeoff, and takeoff was perfectly normal.
Mark, I had a similair experience several years ago flying back from the EAA flyin at Dinwiddy County Airport near Petersburg, Va. I landed at Bay Bridge, Md on my return flight home for fuel. While I taxied out to the active I noticed a bumping on the left side that got really bad quickly, the tire was flat as a pancake. My experience was identicle to yours, it was Sunday on the island, Western Auto was open and sold me a tube for a riding tractor front wheel,----- exact size. This happened in 02, however I had the same thing happen last summer after a short hop to Pittston, Nj. By that time I smartened up and had a spare tube from my pevious experience. Neither time did I have a hole------------the tube was pinched---------like it had an overlap. Ken Wiltrout Kutztown, Pa
