Iím experiencing a problem with an inner tube Iíve never had to deal with before. I had a slow leak on the tire facing side of the tube and I patched it. That patch is holding fine and not causing any problems. But after not riding that bike for about a week, I noticed that the tire had suddenly gone flat again. At first, I assumed that the patch had come off, but after taking it all apart and checking the tube, I discovered that there was a new puncture, and it was located on the side of the tube facing the rim. I inspected the rim carefully and couldnít find any sharp edges.
The puncture is located right above one of the spokes, so I thought maybe a spoke was protruding. That didnít seem to be the case. I even took it to the bike shop to have them look at it. They couldnít find the cause either and said it all looked fine. I put a patch on the hole and put it all back together. After about 4 hours, it suddenly went flat again. For some reason, the patch was being pushed from the sides so that the patch formed a wrinkle in the middle, exposing the puncture. I tried the whole thing twice again using larger patches and got the same results. This is getting very frustrating!
The only other thing to try is a new inner tube. But without knowing what caused the puncture in the first place, Iím afraid it will just go to waste if it goes flat right away. After all, I hadnít ridden the bike for about a week before the tire suddenly went flat. Why would that happen? And why arenít the patches working? Can they not be used on the rim facing side of the tube for some reason?
