Thanks guys. I guess the lack of tread just makes me think is begging for a flat, and yet 80% of my riding is going to be on pavement, and I do not plan to ride in mud. Specialized claims these tires have "Flak Jacket" and then they fail to explain what that means. I love their bikes but their site is total amateur in that regard, in spite of how it looks, their site is super unhelpful in many ways. They also state the inner tubes are "standard" so I think I'll upgrade those to make myself feel better. I like the tires I was just worried about how durable or puncture resistant they might be.
