I have the traditional schwalbe marathons. put simply they are the ****.

I keep them year round on my commuter, a late 80s bianchi axis. it's a heavier, steel-framed bike so I'm not worried about the additional weight of the tire. The tires themselves are nearly puncture resistant. I used to frequently get flats riding on Chicago's crappy roads, I switched to schwalbe marathons and have been golden ever since. I got my 1st flat in maybe 3 years last night.
