For tough tire/rim combinations always start prying at the valve stem. If the valve stem is opposite where you start it will keep the tire from finding center (opposite of where you are prying) and deprive you of the sometimes precious millimeter or two of slack. The reverse is true of putting tough tires on; always finish at the valve stem.
