Patent ID: 7802976

Claim:
A mold for molding a tire, with the mold for molding a tire tread comprising a plurality of segments divided in the tire circumferential direction, said segments capable of moving in the tire radial direction, said segments being provided with further divided pieces, and the molding of a pneumatic tire being conducted by the closure of said mold, wherein said each piece is slidable in the tire circumferential direction, right after said mold of a cycle of a tire molding process in which said mold opening and closure are repeated is closed, on an end surface in the circumferential direction of said each piece in said segment, there are a contact part that contacts with the end surface in the circumferential direction of the adjacent piece, and a non-contact part that does not contact with the end surface in the circumferential direction of said adjacent piece, said non-contact part is arranged inside of the tire radial direction, said contact part is arranged further outside in the tire radial direction than said non-contact part, a non-contact surface substantially parallel to the tire radial direction of said non-contact part is a rough surface having random concaves and convexes with a height of about 50 to 200 μm, and right before said heated mold is opened irk the cycle of said tire molding process, the end surface in the circumferential direction of the pieces in said segments contacts with the end surface in the circumferential direction of the adjacent pieces at said non-contact part as well.
