After all the component parts of the tire have been
assembled-high-stretch Gum-Dipped cords—plies—beads
-two Extra Gum-Dipped Cord Plies under the Tread-
and the Tread Rubber itself-the tire is placed in a gigantic
curing mold.
In this final important operation, the tire is forced by 43
tons pressure into the Firestone non-skid tread pattern
engraved in the steel mold and vulcanized by steam at
270° F.
