Okay, I'll fess first. I'm not your standard tourist. I don't do things the way everybody else does. Year round, here in New Hampshire, I use Bontrager T2 700x25. I generally can get 5-10,000 miles on them without much trouble. Recently I have been running into trouble I'm not sure how much of that is simply being in the wrong place at the right time. At the end of October I got a flat...ran over a roofing nail and it stayed right in the tire. They are semi slicks but they handle well, year round, and I get plenty of wear out of them.
