Patent ID: 8689843

Claim:
A tire comprising: a tread extending from a first tread edge to a second tread edge and having a plurality of blocks defining a plurality of lateral grooves, each of the plurality of lateral grooves having a groove width, as measured in a substantially circumferential direction, that is less than a width of an adjacent tread block, as measured in a substantially circumferential direction; the lateral grooves having a groove bottom defining a radial groove depth, a first trailing side extending outwardly from the groove bottom to a first trailing edge, and a first leading side extending outwardly from the groove bottom to a first leading edge; a first peak disposed in at least one lateral groove, the first peak comprising a first peak wall that is generally planar and angled with respect to the radial direction extending outwardly from the groove bottom and a second peak wall that is generally planar and angled with respect to the radial direction extending outwardly from the groove bottom, the first peak terminating at a radially outer end and terminating at an axial distance from an equatorial plane less than or equal to one half a tread width, and the first peak having a height between 25 percent and 75 percent of a depth of the at least one lateral groove; and a second peak disposed in the at least one lateral groove circumferentially adjacent the first peak, the second peak comprising a third peak wall that is generally planar and angled with respect to the radial direction extending outwardly from the groove bottom and a fourth peak wall that is generally planar and angled with respect to the radial direction extending outwardly from the groove bottom, the second peak terminating at an axial distance from the equatorial plane less than or equal to one half a tread width, and the second peak having a height between 25 percent and 75 percent of a depth of the at least one lateral groove.
