System for manufacturing a support structure

A system for curing a portion of a tire assembly includes:

• an axially placement shaft;
• a first actuator slid onto the axial placement shaft;
• a first retainer plate adjacent the first actuator on the axially placement shaft;
• a core on the axially placement shaft;
• a plurality of first inserts each axially and radially engaging a radially outer surface of the core with first ends of the first inserts axially engaging the first retainer plate;
• a plurality of second inserts each axially and radially engaging the radially outer surface of the core with first ends of the second inserts axially engaging the first retainer plate, each second insert disposed circumferentially between two of the plurality of first inserts;
• a second retainer plate securing opposite second parts of the first inserts and opposite second parts of the second inserts to the axial placement shaft;
• and
• a second actuator slid on to the axial placement shaft.
