To adjust the firmness of a tire insert, use a standard, hand-held, single hole punch. If an insert is too firm, punch out evenly spaced holes starting along the center of the insert. How much material you remove will determine how soft the insert gets. Just be sure that the hole spacing is uniform so the insert stays balanced and is equally firm all the way around.
