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?
Have you seen something like this before and have input on what could of happened. Let her know!
