I think the ideal width for a commuter tire is 28 or 32, but people disagree on this. Wider tires give you a more comfortable ride and can handle potholes better; narrower tires give you more speed. It's all a trade off and you just have to decide what's important to you. Most would agree that knobbies are a bad idea unless your commute is mostly on dirt trails. Knobbies are less stable on pavement (because less rubber has contact with the road) and they increase drag. "
Found this in the advice for new commuters thread. I've been thinking about switching out my Armadillo's for the stock Ritchey Speedmax tires on my CC, but maybe that isn't such a good idea? It just seems like can take potholes better because they're wider, as well as double duty on light off roads. Are knobbies the worst tires that can go on a commuter? I was thinking about buying some fat Vittoria Hyper Radonneurs, but I already have two sets of tires and I don't want to spend the money of the stock tires will do. What's the best plan for my intended use? What's the best all-purpose tire out there?
