    Abstract: The present invention provides a tire with a sacrificial rib to protect the main ribs of the tire's tread by delaying the onset of irregular wear and the growth thereof. The improved tire tread comprises a plurality of main ribs formed by grooves extending generally circumferentially around an outer surface of the tire to form a main tread width for contacting the supporting surface. A sacrificial rib is provided for contacting the supporting surface at each lateral side of the main ribs. The sacrificial rib is separated from the main ribs by a narrow shoulder groove having a groove width not greater than about 1.5 millimeter. The sacrificial rib has a surface width in the range of about 2.5 percent to about 12 percent of said tread width. The sacrificial rib has a recess defined by a radial offset from a transverse or lateral profile of the main ribs. The offset has a value in the range of about 0.50 millimeter to about 2.0 millimeters when the tire is new. A shape factor is used for defining the shape of the sacrificial rib where the shape factor has a value between about 0.10 and 0.50.

    Abstract translation: 本发明提供了一种具有牺牲肋的轮胎，以通过延迟不规则磨损及其生长的发生来保护轮胎胎面的主肋。 改进的轮胎胎面包括由通常围绕轮胎的外表面周向延伸的槽形成的多个主肋，以形成用于接触支撑表面的主胎面宽度。 提供牺牲肋用于接触主肋的每个侧面处的支撑表面。 牺牲肋通过具有不大于约1.5毫米的槽宽度的窄肩槽与主肋分离。 牺牲肋的表面宽度在所述胎面宽度的约2.5％至约12％的范围内。 牺牲肋具有由主肋的横向或侧向轮廓的径向偏移限定的凹部。 当轮胎是新的时，偏移值在大约0.50毫米到大约2.0毫米的范围内。 形状因子用于限定牺牲肋的形状，其中形状因子具有在约0.10和0.50之间的值。

    Abstract: The present invention provides a pneumatic tire having a tread portion comprising a plurality of axially spaced apart essentially longitudinal grooves separating essentially longitudinal ribs. On at least one of said ribs, transverse grooves or cuts repeat in the circumferential direction to form first and second land portions wherein the first land portions comprise blocks having a circumferential length greater than that of the second land portions. Said second land portion acts as a sacrificial bridge which provides traction improvement and minimizes undesirable surface anomalies during the service life of the tire.
