Abstract
A tire tread comprises elements in relief which are provided with undulated or broken line incisions. These incisions, which are of a width of less than 1 mm, have smaller amplitudes at the bottom of the incisions than at the surface of the tread.
Claims10
A tire tread comprising elements in relief which are provided with undulated or broken line incisions of a wavelength and an amplitude which are small as compared with the dimensions of the elements in relief, characterized by the fact that the incisions have smaller amplitudes at the bottom of the incisions than at the surface of the tread, the amplitudes, starting from the surface of the tread, decreasing linearly as a function of the depth.
