flat tire report
Thanks for the replies. The tire was clearly bulging with both of us on the bike and you could feel the bike sway when I came to a stop, so the tire pressure was close to 0, but I didn't actually take a reading when we came to a stop. After 5-7 minutes on the air-up I only had 15lbs....it took about 15 minutes to get up to 38. I suppose I could have run over of a piece of metal or something but there was nothing visible. The tire is an Anakee with about 5000 miles. The puncture was in the tread groove.
