Front:
THE FIRESTONE PATENTED GUM
DIPPING PROCESS IN THE FIRESTONE
FACTORY AND EXHIBITION BUILDING.
A CENTURY OF PROGRESS.
Back:
Firestone Patented Gum-Dipping Process
By this process, eight extra pounds of rubber are added
to every one hundred pounds of high-stretch cord, coating
every fiber in every cord. This is an extra process for
Safety, Strength and Durability-not used in any other tire.
Gum-Dipped High-Stretch Cords withstand road shocks
58% longer-and the Two Extra Gum-Dipped Cord Plies
under the Tread give 56% greater bond between Tread
and Cord Body.
