Looking for opinions as an absolute answer for this is well nigh impossible. Too many uncertainties. I have 3400 miles on my Barcroft Virginia. It came with Stelvios front and back. I had the front tire replaced at 3300 miles - no flats. The original rear tire suffered a sidewall cut at 1500 miles and was replaced with a new tire. The rear tire was replaced at the same 3300 mile mark - no flats on either except for the aforesaid sidewall cut. 14 miles into the new set I got a front flat. I checked the tire very carefully and found no foreign object or cut. Replaced with another tube and so far okay. Today, after 100 miles, I got a rear flat. Again checked the tire very carefully and found no foreign object or cut. In each case I noticed that the rim tape was either the original (front) or the same as when replaced at the 1500 mile mark (rear). I was always under the impression that when changing to new rubber you change the rim tape, which in each case looks pretty worn. Could that be the cause or anyone have any other idea? Incidentally, the rear tire (559) had a 650 tube in it. Any problem with that? Thanks for any thoughts. I love riding, I hate changing tires.

Mike If the rim tape is deformed into a cavity of a hollow rim then it is probable / likely that is the source of your troubles. No need to change rim strips at every tire change if it is in good shape. Does need to be inspected at every tire change. Rubber rim strips are a waste of time. Some light weight rim strips are ok if changed often. Velox tape is most reliable. Speedy

Steve: I pulled the tire off and took a good look at the back rim and that is exactly what I found. Tape ran properly around most of the wheel but was moved over in one area and didn't cover fully one of the cavities. The original tape had lasted 3500 miles without one regular flat (I had one sidewall cut which of course had nothing to do with rim tape). I don't do much mechanical work at all but I noticed the problem right away which raises the issue of what was my LBS looking at (evidently nothing). I just lost my favorite mechanic from there and I think the lack of attention to details from his replacement shows. But, even with the problem with the flat, I got to ride some which makes it a much better day than the days when I don't ride at all. Thanks for your comment.
I use bias tape with a layer of electrical tape on it to hold it in place. The bias tape (same one used in sewing) comes in a variety of widths, is made of cotton or poly (to name but 2) and can be bought very thin. Barring that, I simply use two layers of electrical tape. I've never had a rim side hole in a tube. Both methods are very inexpensive and can be as close as the local fabric shop or hardware stroe. Nothing fancy, nothing imported.
