Hi! My Specialized Expedition has these knobby tires on it. They've got a smooth area down the middles and they're supposed to be for on and off road riding, but I'm pretty sure they're more for dirt riding than the mostly road riding that we're doing this summer.

The knobby tires seemed like a good idea at the time, since we DO get on the dirt once in a while. I know the bike is never going to perform like a road bike, but I'm thinking about different tires as a way to improve things some. I've heard about these "slicks" and "semi slicks," and that they're faster/better on the road. If I want to go faster, will these make enough of a difference on this bike to be worth doing? Can I do this to my bike and still ride on the dirt road next to the canal by our house?

If this is the case, just how much change can I make to my current 26x1.9 tires with knobs? Is there some point where it just won't do any good? Any tire suggestions from you amazing ladies? Does it help to know the bike's specs? http://www.specialized.com/bc/SBCBkM...keTab=techspec

Yes, I can tell already that there's another bike in my future, but I'm not ready to decide on another bike yet -- I'll keep enjoying this one and learning more about the sport for a while yet!
