    Newbie Question: Tire Width vs. Rim width???
    Ok, in reading posts I hear people talking about there being some kind of relationship between rim size/width and the width of cross tire they can fit on the bike. Can someone please explain this to me? I thought a 700c wheel was a 700c wheel, end of story...guess not?

    Wider rims work better with wider tires. Narrow rims work better with narrow tires.

    to be honest i've been riding mtb trails on my cx bike, 35c on a 18mm iner width rim. never had a problem with tire rolling off the rim.

    edit: the tire is labeled 40c (ritchey trailmix), but it measures 35c on that rim.
