New rims and new wheels. All three flats were simple punctures on the rear tire and happened 10 or 12 miles into a ride.
The first flat, I repaired. I ran my finger around inside the tire and found nothing. I figured whatever caused the puncture didn't stick in the tire.
The second flat, when I got it home, I took the tire completely off the rim. Again, I found nothing. At this point I hoped that the two flats were a coincidence, or else the mysterious sharp object had fallen out when I removed the tire.
The third flat, I got serious. I made a mark on the flat tube. Then I lined the tube up with the rim and made a mark on both the tire and the rim. Then I turned the tube around and made marks in case the tube had been facing the other way in the tire. I checked the rim thoroughly. There were no burrs; no exposed spoke nipples. I turned the tire inside out and found nothing embedded in the tread. Finally, I peeled back the rim tape. Et voila! A tiny little bit of a twist tie was stuck under the rim tape.
Moral: Check under the rim tape!
