Post-cure run-flat and/or noise reduction apparatus and method of manufacturing the same

A run-flat tire comprising:

• a. a pair of post-cure run-flat inserts, each of the pair of post-cure run-flat inserts:
• i. is disposed within an inner tire region between a shoulder region and a respective upper sidewall region of a tire;
• ii. extends 360 degrees about a rotational axis of the tire;
• iii. has a circular cross-section;
• and
• iv. is secured to a radially inner surface of an inner liner during a normal inflation condition of the tire.

A method of manufacturing a run-flat tire, the method comprising:

• a. providing a green tire in a tire mold;
• b. curing the green tire in the tire mold;
• c. removing the cured tire from the tire mold;
• and
• d. after the removing the cured tire from the tire mold, positioning a pair of run-flat inserts within an inner tire region between a shoulder region and a respective upper sidewall region of the cured tire so as to secure an exterior surface of each of the pair of run-flat inserts with a radially inner surface of an inner liner between the shoulder region and the respective upper sidewall region such that a cylindrical sidewall included in each of the pair of run-flat inserts and an interior cylindrical cavity defined by the cylindrical sidewall extends 360 degrees about a rotational axis of the cured tire.
