I find it amazing when you look at a well-used bike tyre, how much glass and bits of metal shrapnel are embedded in the rubber. When the tyre is new, the rubber is thick enough that small sharp things don't make it through to the tube, but they stay in the rubber, and as it wears down those same bits of shrapnel start to become a problem. Usually with an older tyre, once you get one puncture, there are many more on the way, so it's time to replace the tyre.
- analog31 4y agoThis may sound a bit geeky, but I occasionally inspect my tires and pull that stuff out. The two offenders are little shark tooth shaped pieces of hard stone, and tiny bits of steel wire that are supposedly from worn out car tires. But it's true that frequent flats are a sign of a worn out tire.
