    what is more important for rolling resistance

    I have 2 sets of tires that i can put on my commuter bike rims

    one is a set of 1.96" knobby tires, dont know the exact tires

    the other set is 2.2" semi slicks, comparable to maxxis hookworms.

    What would be faster, and easier to ride on the road with, the narrow, aggressive tread tires? or the wider, but far less aggressive tires.

    The semi slicks should be far better on the road.

    +1 Comfort and traction is far better than rolling resistance IMHO. Especially important if the pavement on your commute isn't the best or you have to pass over a lot of cracks and grates that could catch a skinnier tire.

    Smoothies will ALWAYS roll faster than knobbies on pavement. Traction in corners, especially gravelly/sandy ones, is problematic either way. Now, a light XC tread on a really good tire will narrow the gap quite a bit to a crappy smooth tire (example: WTB Nano Raptor is 90+% as good as a dept. store smoothie, from personal experience).

    I've heard a lotta good about Kenda Kwest and Maxxis Xenith (26x1.5, both), and my eyes tell me the Michelin Country Rock 1.75 and the Michelin City 1.85 will FLY! The Intense Micro Knobby 2.25 DOES FLY!

    YMMV; and since you're talking about tires you have on hand, this is mainly for theoretical comparison.
