Abstract: 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 invention poses a new and useful way of preventing irregular wear, increasing the useful life of the tire tread, by placing simple sipes in the center region of the tread and complex sipes in the shoulder regions of the tread.
