  • Layered tire tread design for improved coast by noise and traction performance
    Patent number: 9434211
    Abstract: A tire tread having a layered design is provided. In a first layer of the tread, sipes extend transversely to provide traction in the first stage of the wear life of the tread. In a second layer of the tread, the width of the sipes along the circumferential direction is increased to provide for improved traction in a second stage of the wear life. The increased width is provided by a void that opens to a circumferential groove only along one end. Because the void opens only along one end, a decrease in acoustical effects such as drive by noise can be provided.
    Type: Grant
