Just wanted to see if this is a wide-spread problem.


I ordered six Michelin Aircomp inner tubes from PBK in late march. Thus far, I have used three of them, and all of three have developed slow leakage problems. The first one did so two weeks ago and cause a pinch flat after my tyre ran over a small pebble. The second one developed this problem this past Wednesday after one week of use, and the third one was mounted on Wednesday and developed a slow leak on my ride today. I used to think these were very trustworthy tubes, but it seems like i really got a bad batch. Does anyone else have this problem?
