I'm not as diligent as I should be about inspecting my tires. That's the one drawback I've found to using fenders; they make such inspections more difficult. But the Marathon Supremes I was touring on allowed at least one through in very short amount of time. Of course, I also pulled a few out
before they made it through to the tube. After my tour, I switched back to original Marathons.
