I got the experience of seeing how a bike handles at 70 mph with air leaking out of my front tire fast. My bike wanted to pull right and hard. I was able to hold a line and not wipe out into a Jersey barrier. Thoughts that were going through my mind were, hoping over the barrier just as I hit. Keeping her upright and not using the front brakes. Getting off the highway as quick as possible. It was a very unsettling experience, but not as bad as a high speed wobble. I pumper her back up, (a few hundred strokes of a tiny bicycle pump) found a loose valve stem, but stopped and check quite a few times on my ride home. Dam, it's good to be alive.
