Last weekend I had my second flat tire at KGSP, Greer, SC. The first time it went flat on the ramp at the FBO. The second time I had just taxied to the end of the 10,000 foot runway and turned for the hold short line and "flub-flub." I know the sound. So glad it went before takeoff. That would be an unpleasant landing surprise. After getting the plane towed the 8,000 feet back to the FBO the hunt started for a fix. It turns out the tire was fine and had a lot of tread on it. The tube had a split in one small spot. The hunt started for a replacement tube. No facility at the field carries GA parts. Luckily Greenville, SC has a few fields and I found one shop at another field that sold me a cheap tube. I will admit that my tires have become a situation where a tire was replaced here with what was on hand and a tube there. I've just decided to replace all my tires and tubes with something I want, but that's a different discussion. At my home field, one of the flight schools carries a spare tire and tube in all the planes. I'm curious if anyone here does the same thing. Have you had an away from home flat tire story you can share as well?
