Tire tread

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.

Shoulder tread for a tire

A tire tread for a pneumatic tire has at least one circumferentially extending rib. The rib has a high siping density to provide flexibility to the rib. To provide support to the rib, circumferentially extending along, and attached to, the side of each rib is supporting chamfer.

A tire has a tread on the outer circumferential surface. The tread has circumferential and lateral grooves defining tread blocks. In at least one tread block, one of the circumferentially extending sides of the block has a multi-planar chamfer.

A tire molding method as disclosed wherein a segmented mold () has lugs () in the shoulder regions of the segments () with complimentary lug extensions () in the sidewall forming annular rings (). The lug extensions () align with and form the appearance of a lug () that extends radially inward well into the sidewall of the tire (). the resultant tire () and the mold () for making the tire () are less costly to fabricate than prior art segmented molds.
