Abstract: An anti-skid stud for insertion into the tread of a vehicle tire is disclosed. The stud comprises a support body part extending in an axial direction and a pin body part, the support body part comprising a bottom portion, a middle portion, and a head portion having an upper surface, wherein the pin body part extends beyond the upper surface of the head portion, and wherein, when viewed in top view onto the head portion, (i) the location of the center of gravity of the head portion is laterally offset from the center of gravity of the bottom portion; or (ii) the location of the center of gravity of the pin body part is laterally offset from the center of gravity of the bottom portion; or (iii) the location of the center of gravity of the pin body part is laterally offset from the center of gravity of the head portion; or (iv) the location of the center of gravity of the middle portion is laterally offset from the center of gravity of the bottom portion.

Abstract: 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.

Abstract: A structure for a tread pattern of a pneumatic tire includes a radially extending pedestal, a first set of cylindrical voids extending radially through the pedestal, a second set of cylindrical voids extending radially through the pedestal, and a radially extending void ring circumscribing the pedestal.
