Provided is a sipe extending into a tire tread, comprising an outer radial portion defined by a first waveform having a first amplitude, a first width, and a first wavelength, and an inner radial portion defined by a second waveform having a second amplitude, a second width, and a second wavelength. The first wavelength may be less than 5% of the length of the sipe or may be more than 100% of the length of the sipe, or the second wavelength may be less than 5% of the length of the sipe or may be more than 100% of the length of the sipe, or the second amplitude may be more than 50% of the first wavelength or may be less than 10% of the first wavelength, or the second amplitude may be more than 50% of the second wavelength or may be less than 10% of the second wavelength. |
