CA 2471995

A tire tread for a pneumatic tire has a center rib and a series of steeply slanted grooves in each side region of the tread, the circumferentially adjacent grooves form blocks extending through the tread side regions. The center rib has a serrated configuration along each lateral side and a supporting chamfer extending from each serration point. Adjacent to each rib chamfer is a chamfer extending from the axially innermost point of the rib at the junction of two adjacent steeply slanted grooves. The rib is provided with high density siping. The tread blocks are siped wherein the siping density decreases from the tread center to the tread shoulders.

Bande de roulement pour pneu, comportant une nervure centrale et une série de gorges fortement inclinées de chaque côté de la bande de roulement, les gorges adjacentes sur la circonférence formant des blocs qui s'étendent sur les côtés latéraux de la bande de roulement. La nervure centrale a une configuration dentelée le long de chaque côté latéral et un chanfrein de soutien s'étendant de tous les points dentelés. Un chanfrein, adjacent à chaque chanfrein de nervure, s'étend entre le point axial le plus intérieur de la nervure et le point de jonction de deux gorges fortement inclinées. La nervure est munie d'entailles à haute densité. Les pavés sont entaillés aux endroits où la densité des entailles diminue de la nervure centrale aux épaulements de la bande de roulement.
