I keep getting blow outs in my front tube and always in the same location: right next to the valve stem. The blow outs look like:
On this same tube, there is wear on exactly the other side of the valve stem. I have checked the tire and the wheel and there doesn't appear to be anything sharp enough there.
What can cause this? I suspect it's something that I'm doing. I'm tired of buying new tubes, as I hear these flats cannot be patched. If it matters, it's a presta valve and I usually inflate to 110 psi, the maximum.
