Flat tires are an inconvenience that I have not experienced for over a year, since I got Schwalbe tires on Oma and Betty Foy.
The cheap tires that came on Mr. Dottie’s Jamis, on the other hand, have had several flats in their lifetime. The most extreme flat happened last week – a clean slice straight across the tire itself. He went back to try to find the culprit, but did not see anything that could have sliced a tire, other than a grated bridge, but that seems unlikely. The problem cannot be a defect with the tire itself, because the tube was also sliced. Any ideas? Has this happened to anyone else?
As an aside, I must note that his Jamis frame is obviously too small for him, and the larger vintage Raleigh frame he recently built up is a much better and more comfortable fit. I don’t know why the bike shop sold him that size – they even had to special order it because the size was not in their inventory. We had no bicycle knowledge at the time, and we followed their recommendations. Boo.
