A tread for a pneumatic tire in accordance with the present invention includes a tread base layer, a first tread cap layer radially outside of the tread base layer, a second tread cap layer radially outside of the tread base layer and both radially outside and axially adjacent the first tread cap layer, a third intermediate layer radially between the tread base layer and the first and second tread cap layers. The first tread cap layer has a protrusion extending radially inward and into the third intermediate layer more than a main body of the first tread cap layer and the second tread cap layer thereby allowing the first tread cap layer to provide the overall tread with enhanced performance characteristics after the main body of the first tread cap layer and the second tread cap layer have worn away.

Pneumatic tire with multi-tread cap

Tire

A tire mold is described that includes a plurality of tread molding segments having an inner surface for molding the tire tread. The mold further includes a plurality of sidewall plates having an inner surface for molding the tire sidewall. The tread mold segments together with the sidewalls cooperate to form a tire molding cavity. The sidewall plate further comprises a slot that extends from the outer surface of the tread segment to the inner mold surface, and has a pin extending from the outer surface of the tread segment. The pin is mounted to a rotatable body which can swivel. The rotatable body further comprises a guide pin which cooperates with a working member to rotate the body into a desired position in order to position the pin in the tire tread to be molded. The working member actuates the rotatable body into various positions.

Tire tread

Tire tread and buttress

A tire tread with elastomeric ground engaging elements having an incision is described. The invention is characterized by at least one of the elements having an incision extending from the tread surface towards the interior of the elastomeric material. The incision splits into at least two incision portions in the interior of the elastomeric material below the tread surface. The incision portions extend away from the tread surface and diverge apart from each other over at least part of their depth.
