Non-symmetrical tread ring parting line mold

A tire mold comprising:

• a plurality of tread mold segments, the plurality of tread mold segments each comprising a first end face, a second end face, and an inner surface, the inner surface of the plurality of tread mold segments comprises a tread-forming inner surface for forming a non-symmetrical tread pattern on a tire, the non-symmetrical tread pattern extends onto one of a pair of sidewalls of the tire, and the tread-forming inner surface of the plurality of tread mold segments comprises a first endpoint of the non-symmetrical tread pattern and a second endpoint of the non-symmetrical tread pattern, the first endpoint of the non-symmetrical tread pattern extends to a first sidewall of the pair of sidewalls of the tire and the second endpoint of the non-symmetrical tread pattern terminates prior to contacting a second sidewall of the pair of sidewalls of the tire;
• a pair of side molds comprising a first side mold and a second side mold, the pair of side molds each comprising a sidewall inner surface for forming one of the pair of sidewalls on the tire;
• the first side mold comprising a first side mold end face in direct contact with the first end face of the plurality of tread mold segments at a first level;
• the second side mold comprising a second side mold end face in direct contact with the second end face of the plurality of tread mold segments at a second level;
• wherein the first level is offset to the second level.

A tread mold segment of a tire mold, the tread mold segment comprising:

• a first end face for contacting a first side mold, a second end face for contacting a second side mold, and an inner surface extending between the first end face and the second end face;
• the first end face of the tread mold segment being vertically displaced lower than the second end face of the tread mold segment in the radial direction;
• and
• the inner surface comprising a tread-forming surface for forming a non-symmetrical tread pattern on a tire, the tread-forming surface extends onto one of a pair of sidewall portions of the tire, and the tread-forming surface comprising a first endpoint of the non-symmetrical tread pattern and a second endpoint of the non-symmetrical tread pattern, the first endpoint of the non-symmetrical tread pattern being adjacent the first end face of the tread mold segment and the second endpoint of the non-symmetrical tread pattern being adjacent the second end face of the tread mold segment, and the first end face of the tread mold segment being displaced as compared to the second end face of the tread mold segment such that the first end face of the tread mold segment extends further down along one sidewall of the pair of sidewalls of the tire than the second end face of the tread mold segment.
