A method of forming a tire that includes providing a mold configured to mold a tire tread and having a sipe-forming element, spaced apart inwardly from an outermost molding surface, that includes a knife edge oriented towards the outermost molding surface and a submerged void-forming portion extending from the knife edge, arranging an uncured tire tread within the mold, molding the tire tread arranged within the mold, and demolding the tire tread from the mold such that the sipe-forming element forms a sipe by the knife edge (48) lacerating a thickness of the tire tread as the sipe-forming element is pulled in a direction toward the outermost molding surface and forms a submerged void arranged below the sipe within the tire tread. A tire including a sipe (30) and a submerged void (32) as described above is also disclosed. |
