    Traction:Roll resistant

    Ok how much difference is tire size going to matter. Im running 1.9 in the front and 2.1 in the back right now. I do mostly hard pack dirt but sometimes it is loose and sometimes rock gardens with loose rock. Mostly hard back with little need for lots of traction.

    So what are you asking? Do you want more traction or not? Or is rolling resistance your concern?

    Yes, tire size affect rolling resistance and traction. The "difference" it makes is completely up to your riding ability, technique and the terrain you ride on.

    The tread design will be the most determining factor in traction & rolling resistance.
    The tire size will determine the weight. The heavier (larger) tires will be harder to rotate because there's more mass.

    My advice: Stick to a smaller size and let the terrain you ride determine the tread design you'll need....

    you are not totally correct. tire size is a big factor in traction. the wider the tires are the more traction you will have, these are good in soft, loose, and rocky trails. the smaller the tire, the faster they are. but you will have alot of trouble going through loose dirt and sand becasue the tire will cut through the dirt/sand. a medium sized tire usually works good. take a trip to your lbs and see what they are running.

    the treads are pretty straight forward, it usually says what they are used for on the internet if you look for tires.

    Best all around tire I have ever used, on any trail in several states is the Specialized Roll-X Pro. Fast, light, and is a generous 2.1", and works in any situation.

    I'll agree about the Roll-X Pros; they are fast, light, have a large air volume and have been excellent for me in most conditions...but I have found they are no good in sticky clay mud conditions...I have a separate set of wheels and tires for that.
