what is the durability/life expectancy of most road tires?
I am currently riding on a set of Folding Vitorria Diamante Pro's and I have yet to have a flat since putting them on 600+ miles ago. This is a new experience for me since when I had the michelin pro 3 race tires on, I had a flat on almost EVERY ride! So needless to say this is a nice change. I was looking at my tires today and noticed several small "nicks" in them and it felt like the contact part of my tire was getting fairly thin. If I can remember correctly I could have swarn reading about people riding on a set of tires for 3,000+ miles? no/yes? Looking at my tires, I'm not sure they would last that long. In fact I was beginning to wonder if I needed to make another order for a set just incase these decide to go out on me. I'm sure the road surface is a deciding factor. I live in Portland Oregon where most of the roads I ride on are fairly good with the occasional rough concrete. I do my best to avoid glass and stay as far away from the for side of the road where all the glass, dirt and "stuff" gets blown to.
