Umm... that's kinda an obvious statement, isn't it? The question is: WHEN is EOL for a particular tire? None of my Schwalbe tires had ever flattened on me. The ones I've ridden the most are the Big Apple - I have almost 3000 miles on them by now. The Marathon Plus mentioned above, have much, much, much better puncture protection than the Big Apples.
