Well, There's Yer Problem...

For the last ten days I've been having one flat after another on my rear tire. It began with a couple of industrial-sized staples that put several holes in the tube. Rather than patch it, I replaced it. Then the real trouble started. I kept getting flats and three times the hole in the tube was in the same spot. No matter how closely I examined the inside of the tire, I couldn't find any reason for the punctures. So I thought I had some bad tubes. Bought new tubes. Still got flats. Sometimes I'd go for two days. Sometimes I'd go for two hours. Very frustrating. Finally took the wheel into the bike shop. The experienced mechanic quickly showed me the glass embedded in the outside of the tire that would slowly work in and puncture the tube. Since I had so much glass he recommended a new tire. So happy now...
