Adding tread rubber stock. When the fabric carcass has been built to the proper number of layers and cushion rubber has been added under the tread, the thick, extra tough tread rubber is added, having been molded to the proper shape by extrusion in a previous operation. Mechanical guides help this builder to put the tread on absolutely straight, so the tire will be in perfect balance. Firestone (General Tires), Akron, Ohio

Molds automatically open. At the end of the curing time, the mold draws the steam out of the airbag, opens the lid and ejects the tire from the tread pattern. Workers need to do nothing but pull out the finished tire and put in another uncured carcass. General Tires, Firestone, Akron, Ohio

Tire recapping. Removing a recapped passenger car tire from a curing mold. Before the curing process the tread surface had been ground down evenly and had a strip of reclaimed camelback rubber attached to it. The plan to recap passenger tires with passenger tires with reclaimed rubber camelback, approved by rubber director William M. Jeffers, was put into effect in February 1943 to reduce the demand for replacement tires and still keep civilian cars in service

Putting tire into curing mold. From the vacuum expander, the potential new truck tire is taken to this "watch-case" curing mold in which it is baked under high heat and pressure for a long time. The exact time and temperature varies with the type and size of tire. The airbag inside the carcass is filled with live steam during this process so that heat is added from both inside and out. The mold contains the tread pattern, or design, as well as all markings which will appear on sidewall. Under this heat and pressure the rubber turns semi-liquid, and flows into every crevice, completely bonding the rubber processed fabric carcass to the cushion, the cushion to the tread. After this operation it is now one unit--a complete tire. Firestone (General) Tires, Akron, Ohio
