Claim:
1. A tire tread comprising at least one tread element comprising a waveform sipe therein, said waveform sipe having a length, a width and a depth defined by its extent into the tire tread, said waveform sipe comprising: wherein said second waveform is the same type of waveform as the first waveform; wherein the second wavelength is different from the first wavelength; wherein said first waveform is a sine waveform; wherein the second amplitude is different from the first amplitude; and, wherein the width of the sipe increases as the depth increases as a continuous linear function; wherein said first wavelength is less than 5% of the length of the sipe; wherein said second wavelength is less than 5% of the length of the sipe; and wherein the second amplitude is less than 10% of the first wavelength, the second amplitude is less than 10% of the second wavelength, the first width is between 0 mm and 5 mm, inclusive and the length of the sipe is between 2 mm and 50 mm, inclusive.
