Today I got a second flat tire in two weeks and I think it's from the same spot. There's nothing in the tire and the puncture in the tube on in the inside of the tube. It's right in an indentation in the rim tape where a spoke is. The tape is still in tact but the dip felt slightly deeper that the rest. There is also no part of the spoke pushing through the tape. Is this simply resolved by replacing the rim tape? I still have the original tape (2005 model year, ~2300 miles on the bike), and it is the quality canvas-like material, not the thin rubber.
The funny part is, I was talking to my coworker about how to fix a flat because he was telling me about his recurring flat, when after about 5 minutes of talking, standing next to my bike (at work, in an office) and the tire decided to speak up with a PSSSSHHHHHHHHTTTT!
