| description | In a first aspect of the present invention, a tire tread is provided, the tread comprising a tread cap comprising a first rubber compound for contacting the road when driving, at least one circumferential groove reinforcement forming at least one of the grooves in the tread cap, the groove reinforcement comprising a second rubber compound for reinforcing an area adjacent the grooves formed by the groove reinforcement, wherein the groove reinforcement comprises for at least one of the grooves formed by the groove reinforcement two groove sidewall layers, each sidewall layer extending from the outer radial surface of the unworn tread down into the direction of the bottom of the groove formed by the groove reinforcement and wherein each sidewall layer has an essentially uniform thickness along its length, and wherein the groove reinforcement comprises a groove support portion forming a bottom portion of the groove and having a radially inner base side as well as a radially outer top side, wherein the groove support portion tapers from its base side to its top side. |
