1. A system for molding a non-pneumatic tire, the system comprising:
a lower mold portion including:
a lower backing plate;a plurality of lower projections extending from the lower backing plate, wherein the lower projections are arranged in a first predetermined pattern to correspond to a pattern of cavities in a first side of the tire;a plurality of lower sleeves configured to at least partially cover the lower projections, the lower sleeves having an external surface and an internal recess having an internal surface, wherein the internal surface of the lower sleeves is shaped substantially similar to an external surface of the lower projections, and the external surface of the lower sleeves corresponds substantially to an external surface of the cavities in the first side of the tire; andat least one lower retention plate configured to be positioned proximate the lower backing plate and retain the lower sleeves on the lower projections; and an upper mold portion configured to be associated with the lower mold portion, the upper mold portion including:
an upper backing plate;a plurality of upper projections extending from the upper backing plate, wherein the upper projections are arranged in a second predetermined pattern to correspond to a pattern of cavities in a second side of the tire;a plurality of upper sleeves configured to at least partially cover the upper projections, the upper sleeves having an external surface and an internal recess having an internal surface, wherein the internal surface of the upper sleeves is shaped substantially similar to an external surface of the upper projections, and the external surface of the upper sleeves corresponds substantially to an external surface of the cavities in the second side of the tire; andat least one upper retention plate configured to be positioned proximate the upper backing plate and retain the upper sleeves on the upper projections.
