So after having no flats for about a year (finally figured out that the Stops Flats 2 brand of tire liners really does stop flats better than other brands and if you buy the right size they don't give you flats either) I'm suddenly having a rash of flats:
#1. It started with a regular puncture flat (only second front tire flat I've ever had and it only happened because I wasn't using a tire liner). I replaced the tube with a brand new one (it's my policy to avoid patching).
#2. That tube exploded. So I replaced it with another brand new one.
#3. That lasted for a day then somehow I got a spoke flat (you know from the spoke poking through the rim tape). Considering I was using the same rims and rim tape for over 1000 miles it seemed like a fluke...I was also outta spare tubes so I just patched the original (unexploded) tube and put it back in.
#4. That tube exploded (in a different area from the first explosion). So I patched another old tube I had lying around and put that in.
#5. That tube also exploded (in yet another area). So I patched another old tube and put that in.
#6. Then I got another spoke flat (again in a different area from the first spoke flat). So I patched it and replaced the 3 layers of strapping tape I was successfully using as rim tape for over 1000 miles with some nice thick cloth hockey tape.
#7. Finally I just got another spoke flat.
I'm at my wits end. There are no burs or pointy areas inside the rim and even if there were I'm now using thick cloth tape that reaches almost from bead to bead. What gives?
EDIT- I'm now up to 11 flats in 9 days:
#8. Another "spoke flat" pinhole (after adding a second layer of cloth rim tape). Removed tire, turned it inside out and cleaned it in the shower (also cleaned rim in shower) to make sure there are absolutely no sharp particles present.
#9. Flat from patch failure. Threw out tube and replaced with different (patched) tube.
#10. Another "spoke flat" pinhole. Patched it and this time tried to be more gentle when scuffing/abrading patch area.
#11. Another "spoke flat" pinhole (this time on opposite side of rim). Replaced 1.25"-1.6" wide tube with 1.5"-1.9" wide tube.
EDIT- Problem was that the tubes were too narrow!
