Tires in use wear in a host of ways. One negative manner in which tires, especially truck tires, may wear is in an irregular fashion. When this phenomenon happens, the tread of the tire may become unusable, forcing the user to replace the tire, which is undesirable. This patent application poses a new and useful way of preventing irregular wear involving the use of hidden sipes or tread blocks. In some embodiments, these hidden sipes or tread blocks are found in tread blocks or ribs adjacent other tread blocks or ribs that have been determined to be susceptible to irregular wear. In other embodiments, the hidden sipes or tread blocks are formed by a sipe blade that has a connecting member to which two y-branched members are attached, and further comprising dividing members that connect between the y-branched members.
